Abstract: All real world control systems must deal with actuator and state constraints. Standard conic sector bounded nonlinearity stability theory provides methods for analyzing the stability and performance of systems under constraints, but it is well-known that these conditions can be very conservative. A method is developed to reduce conservatism in the analysis of constraints by representing them as nonlinear real parametric uncertainty. 1 Introduction All real world control systems must deal with constraints. The control system must avoid unsafe operating regimes. In process control these constraints typically appear in the form of pressure or temperature limits. Further constraints are imposed by physical limitations---valves can only operate between fully open and fully closed, pumps and compressors have finite throughput capacity, surge tanks can only hold a certain volume. One approach to controlling systems with constraints is to optimize the control objective on-line subject to th...
