<P>In many industrial applications, the existing constraints mandate the use of controllers of low and fixed order while typically, modern methods of optimal control produce high-order controllers.&nbsp;The
authors&nbsp;seek to start to bridge the resultant gap and present a novel methodology for the design of low-order controllers such as those of the P, PI and PID types. Written in a self-contained and tutorial fashion,
this book first develops a fundamental result, generalizing a classical stability theorem - the Hermite-Biehler Theorem - and then applies it to designing controllers that are widely used in industry. It contains material
on:</P> <P>• current techniques for PID controller design;</P> <P>• stabilization of linear time-invariant plants using PID controllers;</P> <P>• optimal design with PID
controllers;</P> <P>• robust and non-fragile PID controller design;</P> <P>• stabilization of first-order systems with time delay;</P> <P>• constant-gain stabilization with desired
damping</P> <P>• constant-gain stabilization of discrete-time plants.</P>
