On the Development and Implementation of Parameter-Adaptive Controllers

Abstract

The design of parameter-adaptive control algorithms which are based on proper parameter estimation and linear control algorithms is considered for single-input single-output processes. The resulting adaptive control algorithms work well if some pre-conditions for the stability and convergence are satisfied. In practice these pre-conditions may be violated. Therefore a supervision level is introduced which monitors faulty functions and takes appropriate actions. Further improvements are obtained by designing a “parameter-interface” between the parameter estimation and the controller design. Various steps for the application are considered and software packages and the implementation on microcomputer controllers are described.
