Optimization of fuzzy system performance using sequential quadratic programming

摘要

In this study, the Sequential Quadratic Programming (SQP) is first used to solve the optimal control problem of maximizing system efficiency, which is a global optimization. And then a fuzzy logic controller is developed to implement the optimal control strategy in terms of further tradeoff between engine and battery in local. In addition, the fuzzy system's performance to be improved is by optimizing the fuzzy rules based on the SQP results.
