Test: Construction Of Phase Trajectories - Electrical Engineering (EE) MCQ

Explanation: Electrical time constant is smaller than the mechanical time constant and hence the delay in the mechanical systems is more than the electrical systems.

Explanation: The open loop transfer function of a unity feedback system is used to calculate the conditional stability by using the Routh Hurwitz criteria or the Root locus technique.

Explanation: Peak overshoot refers to the damping of the system as if the damping id less than the peak will be more.

Explanation: The value of the p can be calculated by comparing the equation with the standard characteristic equation.

Explanation: Polar plot can be made of the following function by following appropriate steps and thus the plot neither crosses the real axis nor imaginary axis.

Explanation: If switching is made to occur the crossing of the starting trajectory with the thick line trajectory the system follows the trajectory and reaches the desired output at the minimum time.

Explanation: Suitable logic circuitry has to be added to the controller structure for the kind of the switching and such systems are known as the bang-bang control system.

Explanation: Zeroes are defined as the roots of the numerator of the closed loop system.

Explanation: The effect of zero on transient response will be negligible if the zero moves left from the origin due to dominant pole mechanism.

Explanation: The zeroes on the real axis near the origin are generally avoided in design as they cause system instability.
