Which of the following is an example of an open loop system?
When deriving the transfer function of a linear element
The second derivative input signals modify which of the following?
Which mechanism in control engineering implies an ability to measure the state by taking measurements at output?
Identify the number of poles and zeros of the transfer function whose frequency response is given as:
A two stage amplifier with negative feedback has an overshoot when damping factor K is:
When a unit step input is applied to a perfect integrator, the output
When gain K of the open-loop transfer function of order greater than unity is varied from zero to infinity, the closed-loop system
The pole-zero map of a rational function G(s) is shown below. When the closed contour Γ is mapped into the G(s)-plane, then the mapping encircles
The block diagram of a feedback compensated system is given below: Which of the following statements are correct? a) When Kt = 0, the feedback compensation is in-effective and the system is uncompensated b) When Kt = 0, the feedback compensation is most effective and system is compensated c) The performance of the compensated system depends on Kt and T d) The performance of the compensated system does not depend on T
Based on the given para, answer the following question. Sensitivity considerations often are important in the design of Control Systems. Because all physical elements have properties that change with environment and age, we cannot always consider the parameters of the Control System to be completely stationary over the entire operating life of the system. For instance, the winding resistance of an electric motor changes as the temperature of the motor rises during operation. Control systems with electric components may not operate normally when first turned on because of the still-changing system parameters during warmup. This phenomenon is sometimes called “morning sickness”. Most duplicating machines have a warmup period during which time operation is blocked out when first turn on. A good Control System should be: (a) Very sensitive to parameter variations (b) Insensitive to parameter variations (c) Insensitive to input commands (d) Sensitive to input commands Which of the above are correct?
Which signal will become zero when the feedback signal and reference signal are equal?
When the gain margin and phase margin have values as 0 dB, then the system is:
A system is defined as marginally stable when
