Single Neuron Adaptive Controller for Brushless DC Motor Control System
Abstract:In designing highspeed highaccuracy control system of Brushless DC motor (BLDCM), we encountered several problems: saturation armature reflection, parameter drifts, load disturbances, and stringent requirement on online calculation speed. We propose a linear singleneuron adaptive PID controller as the best we could devise as a solution of these problems. We compared both linear and nonlinear single neuron PID controllers. The comparison is presented in Figs.3 throught 7; it involves five different conditions: noload starting (Fig.3), load starting (Fig.5), inertia change (Fig.4), load disturbance (Fig.6), input change (Fig.7). The comparison shows that the linear single neuron adaptive PID controller is better than the nonlinear one because: (1) the linear one is better in meeting the fast covergence demand for BLDCM control system, (2) the linear one improves better the dynamic performance robustness and adaptive capability of the BLDCM control system.
Keywords:Brushless DC motor (BLDCM)  neuron  PID control
