A servomechanism position control has the plant transfer function
![]()
You are to design a series compensation transfer function D(s) in the unity feedback configuration to meet the following closed-loop specifications:
• The response to a reference step input is to have no more than 16% overshoot.
• The response to a reference step input is to have a rise time of no more than 0.4 sec.
• The steady-state error to a unit ramp at the reference input must be less than 0.02.
(a) Design a lead compensation that will cause the systemtomeet the dynamic response specifications. (b) If D(s)is proportional control, D(s) = kp, what is the velocity constant Kv?
(c) Design a lag compensation to be used in series with the lead you have designed to cause the system to meet the steady-state error specification.
(d) Give the MATLAB plot of the root locus of your final design.
(e) Give the MATLAB response of your final design to a reference step.
