摘要
针对同步磁阻电机系统中的混沌现象,在分析运动特性的基础上,提出了一种自适应控制方法。首先,该方法验证了某些特定的参数和工作条件下系统会出现复杂的混沌运动。然后,对Lyapunov指数图、分岔图和相图进行分析。再以Lyapunov稳定性理论为基础,提出了系统在已知参数与未知参数下的自适应控制器。该控制器克服了以往一般自适应控制器中空置率不连续的缺点,使系统脱离了混沌。仿真结果验证了理论分析的正确性以及该方法的可行性,对研究优良的控制方法提供了理论参考。
Aiming at the chaotic phenomenon in the system of synchronous reluctance motor, an adaptive control method is proposed in this paper on the basis of analyzing the motion characteristics. First, in some cases with certain parameters, it is verified that the system will appear complicated chaotic motion. Then, the Lyapunov index map, bifurcation diagram and phase diagram are analyzed. Then, based on Lyapunov stability theory, an adaptive controller is proposed in the system with known or unknown parameters, which overcomes the disadvantages of the vacancy rate' s discontinuity between general adaptive controller. The simulation result verifies the correctness of the theory analysis and the feasibility of this method. Meanwhile, it also provides a theoretical reference for the study of excellent control method.
