Homework Set #4 (ECE743) 1. Problem 1: Consider the electromechanical system shown below: where, g is the value of x at which the spring is at rest. Assume that V is generated by a voltage source with the following waveform: 1 K = 2667 N/m D = 10 Ns/m N = 500 T m = 0.8 kg d = 1E-4 m g = 3E-4 m R = 10 A = 2E-4 m 2 f ext = 0

Unformatted text preview: voltage is zero. Use the trapezoidal integration method with = 0.1 s. Perform the following: a) Give the state-space equations for the above system. b) The trajectory and plot of V(t), x(t), dx/dt, i(t) and f em (t) with the trapezoidal input and x 0 = g (the spring is at rest). c) The same as part b), except with no input and x = 0 (the spring is at maximum stretch). 2...
