碩士 === 元智大學 === 電資與資訊工程研究所 === 86 === The main purpose of this thesis is to analyze the limit cycles of nonlinear multi-input multi-output control systems. An extension of the stability-equation method is proposed to find the amplitudes and frequencies of limit cycles. When a multi-input multi-output control system is symmetrical, it can be converted into multiple singal-input singal-output control systems first, then the stability-equation method is applied. For illustration, both two-input two-output systems and three-input three-output control systems are considered. In addition, a system with six nonlinearities is analyzed. All the results are checked by computer simulations.
