摘要：
A description is given of the application of two digital parameter adaptive controllers to a pH process. The controllers result from proper combinations of recursive parameter estimation algorithms with a controller design procedure, for which the controller parameters can be calculated with small computational expense after each sampling. The different software modules for parameter estimation, controller design, etc. have been implemented on a microcomputer-based digital controller. The resulting control behavior with the digital parameter adaptive controllers is shown and compared with the control behavior of an analog PI-controller.
