摘要：AbstractThis paper deals with the design of Proportional-Integral (PI) and Proportional-Integral-Derivative (PID) controllers. The main result is a constructive determination of the setSγ of stabilizing PI and PID controllers achieving anH∞ norm bound of γ on the error transfer function. This result utilizes the computation of the complete stabilizing setSrecently obtained. We also point out connections between thisH∞ design and Gain and Phase Margin designs. Illustrative examples are presented.
