The differential equation for the computer control feedback system of an electromechanical device is given below. Where u(t) is the input and y(t) is the output of the system. (Note: The transfer function will be G(s)=y(s)/u(s) ). d^3y(t)/dt^2 + 6 d^2y(t)/dt^2 + 9 dy(t)/dt = 9 du(t)/dt + 9u(t) If an input 15 volts supplies to the above system determine the output voltage when natural frequency is 3 rad/s. Enter the output voltage value (volts) in the box below: Answer:

Consider the coil shown in the figure below. The voltage supply is equal to: u(t) = i(t)R + dψ(t)/dt Assuming that the inductance of the coil is constant, the above equation is: u(t) = i(t)R + Ldi(t)/dt This is a linear 1st order ODE. What is the response of the current to a change in voltage, assuming zero initial conditions? Develop the system differential equation and use Simulink to find the system's step response.

The purpose of an Automatic Voltage Regulator is to maintain constant the voltage generated in an electrical power system, despite load and line variations, in an electrical power distribution system. Figure P5.31 shows the block diagram of such a system. Assuming Ka=10, Ta=0.1, Ke=1, Te=0.4, Kg=1, Tg=1, Ks=1, Ts=0.001, and the controller, Gpid=1.6+0.4/s+0.3s, find the closed-loop transfer function T(s) of the system, expressing it as a rational function.
