Abstract

<abstract abstract-type="main" id="acs2444-abs-0001"> <title>SUMMARY</title> <p id="acs2444-para-0001">In this paper, a loop‐shaping design method of PID controllers is proposed for stable plants under the condition that the plant is linear time invariant and a finite‐time plant response is available. The integral gain of the PID controller is maximized subject to a stability margin constraint, and the optimal solution can be found by linear programming. A filter bank is used for extracting useful information from the finite‐time response data. Numerical examples show that this method is applicable to a wide range of plants including non‐minimum phase and/or time‐delay plants. Copyright © 2013 John Wiley &amp; Sons, Ltd.</p> </abstract>
