Abstract :
The authors consider the use of a multiple controller structure in an attempt to achieve fault-tolerant control of a power system. The controller consists of a model reference adaptive controller in parallel with a conventional power system stabilizer. The adaptive system is based on an adaptive controller originally developed to stabilize unknown linear systems with relative degree one or two and modified to operate in the presence of bounded disturbances and high-frequency unmodeled dynamics. System closed-loop behavior is studied via simulation in the presence of significant load induced plant uncertainty as well as failure of the conventional power system stabilizer. Significant improvement in closed-loop system behavior is noted during normal operation as well as during load peaks and conventional stabilizer failure
