Electrical Engineering: Control system MCQ
A stable LTI system with single pole P, has a transfer function G(s)H(s) = S2+100 / (S-P) with DC gain of 5; the smallest possible frequency in radian/sec at only gain is
A PMDC motor is connected to 5 V at t = 0. Its speed increases from 0 to 6.32 rad/sec monotonically from t = 0 to t = 0.5s and finally settles down to 10 rad/sec. Assume negligible armature inductance. Find the transfer function?
For the given open loop transfer function K/(s+a)(s-b)(s+c). If 1+G(s)H(s) plane encircles the origin once in counter clockwise direction then number of closed loop poles in right side of s-plane will be
