Question

2. The following second-order transfer function was obtained via an identification experiment performed in a small neighborhood of a particular stead-state operating condition of a nonlinear process: G(s) = (3s +1)(6s1) (a 5pts.) Use direct synthesis method to design a controller. Assume that the desired closed-loop transfer function is first order and the desired closed-loop time constant is Td = 4. (b 5pts.) Suppose as a consequence of the nonlinearity, this process sometimes passes through a region of operation where the true process has a transfer function of the form: K(1 -as) 3s + 1)6s+ ) G(s) (0.2) If the controller designed in (a) is implemented on the process described by (0.2), find the condition on the value of unknown parameter a that makes the closed-loop system stable.
