1. Consider a mass-spring-damper system (i.e., the plant) described by the following second-order differential equation ÿ+3y+y=u (1) where y represents the position displacement of the mass. Our goal is to design a controller so that y can track a reference position r. The tracking error signal is then e(t) = r − y(t). (a) Let there be a PID controller •t u(t) = Kpe(t) + Ki S e(T)dT + Kɖė(t). (2) Derive the closed-loop system equation in forms of ODE. (b) Draw the block diagram of the whole system using transfer function for the blocks of plant and controller. Compute the closed-loop transfer function from the block diagram.
