Design of multivariable industrial control systems by the method of inequalities

Abstract

This chapter reviews the application of the method of inequalities to the multivariable control of important industrial processes such as distillation columns, a turbofan engine and power systems. It is shown that desired performance and stipulated constraints can be expressed in terms of a conjunction of inequalities, any solution of which gives an acceptable design. The method of inequalities is consistently shown to give an efficient solution to the given problem, not only in terms of the ease of problem formulation, but also because of the simple and implementable controllers obtained. © 2005 Springer-Verlag London Limited.
