【摘要】 在分析无刷直流电机的数学模型的基础上,建立了控制系统的SIMULINK仿真模型,提出了无刷直流电机调速系统单神经元自适应控制方法。该方法在调速系统中,电流环采用滞环电流控制,转速环采用单神经元自适应控制器控制,实现了双闭环自适应控制的调速系统。仿真结果表明:这种新型的控制方法响应快、无超调、鲁棒性强,较传统PID控制具有更好的动、静态特性。更多还原

【Abstract】 According to the mathematical model of BLDCM,a single neural selfadaptive control method was proposed for controlling the speed servo system based on the Simulink dynamic model of BLD CM. In the system,the hysteresis current controller was implemented in the current loop,and in the speed loop a single neural selfadaptive controller was applied. Organically combined the blocks,a test was per formed on a adaptive control system of double close loops. The simulation results show the improved per formance is superior to the traditional PID controller. It works well with high dynamic and static perfor mance,because of its advantage in quick response.更多还原
