A simple model of an electromecanical actuator is
0.06z + 5.5z+3100z+4.6l
0.01l+4l+ein (t)-2.3z
Where z is the position of the mechanical mass-spring-damper subsystem (in meters) and i is the current in the solenoid armature circuit. The single input to the system is source voltage e in (t)
a. use matlab to obtain the frequency response of the mechanical actuator (position z) if the source voltage is ein(t)=8sin 150t V
b. use MATLAB to compute the bandwidth of the electromechanical actuator
