Question

uge6 of7 Problem 5 (Seven points if only the correct answer is circled. Four points if two answers are circled and one is correct.) armature current of a de machine is controlled with a PI controller. The controller is The designed to cancel the electrical time constant. The following is known about the machine: KrWM = 15 (PWM converter gain) 0b- 2400 rad/s (system bandwidth) a) What is the armature inductance? R.-2.0 Ω (Armature resistance) e 16 ms (electrical time constant) 16m 16m 111) 16m iv) 16m-2 b) What is the integral gain (Ki) for the system? ii) 1 200160m)400 15 2400.2 ii 1) 15 2400-16m 2-15 15.2 2400 16m iii) In terms of the integral time constant (K), what is the proportional time constant? i) 16m.K iv) 16m Kt 2 c) 2400 2400 16m 111)
