Znanost koja proučava automatizirane procese naziva se
Correct Answer
B. Automatika
Explanation
Automatika je znanost koja proučava automatizirane procese, što uključuje razvoj, upravljanje i kontrolu sustava koji rade samostalno ili poluautomatski. Kibernetika je znanost koja se bavi proučavanjem sustava i regulacijom informacija, dok mehatronika kombinira područja mehanike, elektronike i informatike. Robotika se bavi dizajniranjem, izgradnjom i upravljanjem robotima. Budući da se u pitanju traži znanost koja proučava automatizirane procese, to je najbolje opisano odgovorom "automatika".

Automatizirani procesi zamjenjuju čovjeka u fizičkom i umnom radu.
Correct Answer
A. Točno
Explanation
Automated processes replace humans in physical and mental work. This means that tasks that were previously performed by humans are now being carried out by machines or computer systems. Automation allows for increased efficiency, accuracy, and productivity in various industries. It reduces the need for human intervention and can perform tasks faster and more consistently. As a result, it can free up human workers to focus on more complex and creative tasks.

Uređaj za vođenje
Correct Answer(s)
A. Prati djelovanje procesa i usmjerava ga prema zadanom cilju
C. Zamjenjuje čovjeka u opažanju
Explanation
The correct answer is "prati djelovanje procesa i usmjerava ga prema zadanom cilju" and "zamjenjuje čovjeka u opažanju". This means that the device for guidance monitors the operation of the process and directs it towards the desired goal, and it also replaces human observation.
5.
Ljudsko opažanje u sustavima zamjenjuju uređaji koje nazivamo
Correct Answer
B. Senzori
Explanation
Sensors are devices that replace human perception in systems. They are designed to detect and respond to physical inputs such as light, sound, temperature, pressure, etc. By converting these inputs into electrical signals, sensors provide valuable information to the system, enabling it to make decisions and take appropriate actions. Therefore, sensors are the most suitable option among the given choices to replace human perception in systems.
6.
Ljudsko odlučivanjeu sustavima zamjenjuju uređaji koje nazivamo
Correct Answer
A. Mikrokontroleri
Explanation
The correct answer is "mikrokontroleri". In the given question, it is stated that "Ljudsko odlučivanjeu sustavima zamjenjuju uređaji koje nazivamo". This translates to "Human decision-making in systems is replaced by devices called". Among the options provided, "mikrokontroleri" is the only option that fits the sentence and makes sense, as it refers to microcontrollers which are devices used to automate decision-making processes in various systems.
7.
Ljudsko djelovanje u sustavima zamjenjuju uređaji koje nazivamo
Correct Answer
C. Izvršni članovi
Explanation
In the given question, the correct answer is "izvršni članovi" which translates to "executive members" in English. This answer is appropriate because it refers to devices that replace human actions in systems. The other options, such as "mikrokontroleri" (microcontrollers), "senzori" (sensors), and "usporednici" (comparators) do not accurately represent the devices that replace human actions in systems. Therefore, "izvršni članovi" is the correct answer.

Pojam kibernetika je uveo američki matematičar Norbert _________________ u djelu Kibernetika (Cybernetics, 1948)
Correct Answer(s)
Wiener
Explanation
The correct answer is "Wiener." This is because the question is asking for the name of the American mathematician who introduced the concept of cybernetics in his work "Cybernetics" in 1948, and the name of the mathematician is Norbert Wiener.
10.
Slika predstavlja...
Correct Answer
C. Sustav
Explanation
The given answer "sustav" is correct because the image represents a system. A system is a collection of interconnected components or elements that work together to achieve a specific purpose or function. In the image, there are multiple components or elements that are interconnected and working together, suggesting that it represents a system rather than a product process, energy transfer, or regulator.
11.
Upravljive veličine u sustavu su
Correct Answer(s)
A. Procesne veličine
D. informatičke veličine
Explanation
The correct answer is "procesne veličine" and "informatičke veličine". Upravljive veličine refer to the variables or quantities that can be controlled or manipulated in a system. In this context, "procesne veličine" refers to the variables related to the process or operation of the system, while "informatičke veličine" refers to the variables related to the information or data in the system. These two types of variables are considered as the manageable or controllable variables in the system.
12.
Negativnu povratnu vezu imaju svi sustavi.
Correct Answer
B. Netočno
Explanation
The statement "Negativnu povratnu vezu imaju svi sustavi" translates to "All systems have negative feedback." The correct answer is "Netočno" which means "False." This suggests that not all systems have negative feedback, implying that there are some systems that do not utilize negative feedback in their functioning.

Označi točne tvrdnje za otvoreni automatski sustav:
Correct Answer(s)
A. Ne prati izlaznu veličinu
B. Osjetljiv na smetnje
E. Nema NPV
F. Nema regulacije izlazne veličine
Explanation
This question is asking for the correct statements about an open-loop control system. The correct answer states that an open-loop control system does not track the output value, is sensitive to disturbances, does not have a NPV (Negative Predictive Value), and does not regulate the output value. Therefore, the correct statements for an open-loop control system are that it does not track the output value, is sensitive to disturbances, does not have a NPV, and does not regulate the output value.
14.
Označi točne tvrdnje za zatvoreni automatski sustav:
Correct Answer(s)
C. Regulira izlaznu vrijednost pomoću NPV
D. Ima NPV
Explanation
The correct answer is "regulira izlaznu vrijednost pomoću NPV" (regulates the output value using NPV) and "ima NPV" (has NPV). This means that the closed-loop automatic system is able to regulate and control the output value using the NPV (negative feedback) principle. It also indicates that the system has NPV, which is a measure of the difference between the desired value and the actual value of the output.
15.
Prilikom regulacije usporednik kao izlaznu vrijednost daje
Correct Answer
C. Regulacijsko odstupanje
Explanation
During regulation, a comparator gives the output value of the regulation error, which is the difference between the desired value and the actual value. This regulation error is known as "regulacijsko odstupanje" in Croatian. Therefore, the correct answer is "regulacijsko odstupanje".
16.
Izvršni član na temelju upravljačkog signala iz regulatora...
Correct Answer
D. Mijenja količinu ulazne energije
Explanation
The correct answer is "mijenja količinu ulazne energije". The executive element, based on the control signal from the controller, adjusts the amount of input energy to the system. This means that it modulates the input energy to achieve the desired output or response from the system.
17.
Odstupanje dobivene vrijednosti na izlazu od željene vrijednosti u regulacijskom krugu nazivamo _______________ _____________.
Correct Answer
regulacijsko odstupanje
Explanation
The term "regulacijsko odstupanje" refers to the deviation or difference between the desired value and the actual value at the output of a control loop or system. It represents the error or discrepancy between the setpoint or target value and the measured or obtained value in a regulation process. This term is commonly used in control engineering to assess the performance and accuracy of a control system in achieving the desired output.
18.
Mjerno osjetilo je zaduženo da izlaznu vrijednost pretvori u naponski signal.
Correct Answer
B. Netočno
Explanation
The given statement is incorrect. The correct statement should be "Mjerno osjetilo je zaduženo da ulaznu vrijednost pretvori u naponski signal." This means that the measurement sensor is responsible for converting the input value into a voltage signal, not the output value.
19.
Dio regulacijskog kruga koji na temelju vrijednosti regulacijskog odstupanja generira upravljački signal naziva se
Correct Answer
B. Regulator
Explanation
The correct answer is "regulator". In a control system, the regulator is responsible for generating the control signal based on the error between the desired and actual values. It compares the setpoint (desired value) with the feedback (actual value) and adjusts the control signal accordingly to minimize the error and maintain stability in the system. The regulator plays a crucial role in maintaining the desired performance and stability of the control system.
