无刷直流电机调速系统的最优状态反馈控制研究

本文研究具有量测噪声和负载干扰的无刷直流电动机实时最优速度控制方法。首先建立系统的硬件结构，并推导出系统的数学模型；接着采用卡尔曼滤波器的状态估计；提出了一种基于动态规划的最优反馈控制策略；最后给出了补偿量测噪声和负载干扰的自适应算法。仿照结果表明，提出的方法，在广宽的调速范围内，系统具有较好的静动态性能。验证了提出方法的有效性与可行性。

Study on Optimal state Feedback Control of Brushless Direct-Current Motor Drive Systems

This Paper develops a unified methodology for real-time speed control of a brushless Direct-current motor drive system in the presence of measurement noise and load torque disturbance. At first , the mathematical model and hardware structure of system have been established . Then an optimal state feed back controller using the Kalman filter state estimation technique is derived. This is followed by an adaptive control algorithm to compensate for the effects of noise and disturbance .These two algorithms wor...
