摘　　要：针对含随机扰动的方波型无刷直流电机的电压跟踪,引入饱和向量值函数及自适应参数,设计一种简单的、含饱和项的自适应非线性控制器克服电压跟踪中出现的电压饱和现象及抑制随机扰动,使受控系统跟踪参考电压信号.从理论上论证受控系统在设计的控制器作用下是全局一致毕竟有界.数值实验显示该控制器能使受控系统实现扰动衰减,电压跟踪效果较好.For the problem of voltage tracking on the trapezoidal brushless DC motor （BLDCM） with stochastic disturbance, a simple adaptive nonlinear controller with a saturation term, which can overcome the phenomena of voltage saturation and stochastic disturbance arising from voltage tracking and make the controlled system track the reference, was designed by introducing a saturation function and an adaptive parameter. Theoretically,the sys- tem is globally uniformly ultimate bounded. Numerical experiments show that the controlled system can achieve disturbance attenuation with satisfactory voltage tracking.
