碩士 === 國立臺灣科技大學 === 機械工程系 === 89 === The purpose of this paper is to propose an adaptive controller for induction motor control system. Some of the system parameters are assumed to be unknown time varying without any information of their variation bounds. Traditional adaptive control algorithms are not application to this kind of systems due to their time-varying nature. Here, a function approximation based controller is designed to transform the time-varying parameters into a linear combination of known orthonormal basis. Besides, the singularity problem of the decoupling matrix is dealt with by redesigning the parameter update algorithms. Simulation cases shown that the proposed schemes have excellent performance.
