On control system design: a comparative study

The linear algebraic method for designing control systems was introduced in the Magazine (Cen,1987, and Chen and Seo, 1990). In this article, the method is compared with designs using Q-parameterization and then compared with designs using pole-placement and model (pole-and-zero) matching. It is shown by an example that the method may also yield a better result than the quadratic optimal and the H/sub /spl infin// methods if the design specifications are given in terms of rise time, overshoot and the constraint on the actuating signal.<
