Numerical method for the design of insensitive control systems

A design method has been developed that enables the designer to satisfy random and transient specifications for linear plant, subject to parameter variations. The controller structure is determined by the designer, who can thus incorporate specific features such as integral control. The method uses efficient numerical procedures. Controllers are designed for fairly large superheater problems. It is shown that insensitivity to plant parameter changes can be obtained with very little loss in nominal performance. Computational details of the method are discussed.
