Designing a PD Controller to Specifications

Standard second-order step response that students will demonstrate with controlling a dc motor.

Students learn to design a PD (proportional-derivative) compensator based on specifications to control position. In the lab students first study the derivation of the transfer function, peak time, and overshoot. Then, they complete an in-lab activity to track a reference position square wave using PID control, and observe the effects of disturbances when using using PD and PID control.
