System Optimization---Self-Adaptive Controller for Digitally Controlled Thyristor Converters

A self-adaptive controller is described which can automatically adjust the regulatable parameter values in a digital or discrete-data control system to obtain an optimized response with respect to given operating criteria. Problems where system configuration and transfer function are unknown can be handled by a model which emulates the system elements. The controller uses a traditional hill-climbing search procedure effectively implemented in real time by low-cost microprocessor.
