摘要

提出了一种用于永磁无刷直流电动机驱动的模糊预补偿PI (FPPI)速度控制器。详细讨论了基于DSP实现PMBLDC电机驱动系统的逆变器、位置和电流传感、基准电流产生和PWM电流控制等各个方面。本文所采用的模糊逻辑算法由于简化了规则库的处理方式,并且在去模糊化过程中大大减少了计算量,因此特别适合于数字控制。利用FPPI速度控制器与传统PI速度控制器比较了驱动系统的瞬态性能。

Fuzzy Pre-compensated PI Controller for PMBLDC Motor Drive
This paper presents the fuzzy pre-compensated PI (FPPI) speed controller for permanent magnet brushless DC (PMBLDC) motor drive. Various aspects of DSP based implementation of PMBLDC motor drive system such as inverter, position and current sensing, reference current generation and PWM current control are discussed in detail. The fuzzy logic algorithm used in this work particularly suitable for digital control because of the simplified way of handling the rule base and considerable reduction of computation during defuzzification process. Transient performance of the drive system obtained using FPPI speed controller is compared with the conventional PI speed controller.
