Pole Placement for Time-Delay Systems with Low-Order Controllers a Parameter Space Approach

Abstract:

This paper discusses the pole placement with low-order controllers, e.g., PID type controllers and phase lead/lag compensators, using parameter space approach. The damping ratio sector region and the relative stability region in s-plane, which form a trapezoid region in the left-half of s-plane, are mapped into the controller parameters space. Thus, the corresponding controller parameters can place all the closed-loop poles in a specified trapezoid region, and guarantee the performances of the closed-loop systems. The advantage of the proposed method is that it is simple and can be applied to time-delay systems. A simulation example is given to illustrate the effectiveness of the design.
