方波无刷直流电机恒功率模糊控制

从恒功率的基本定义出发，提出实现电机恒功率运行的数字控制方法。基于该方法的数学模型的强耦合性，该方案中引入了模糊控制策略，设计了稳定的模糊控制器。实验和仿结果证明了该方案的正确性和可行性较和较强的鲁棒性，该方法无需改动硬件，操作方便，为实现电机恒功率运行提供了新的途径，这种设计思路也适用于其它电机。

Control Square Wave BLDCM Running in Constant Power Way

Based on the basic definition of constant power,the paper sets forth a novel digital control way to make motor run in constant power.Constant power loop is added into original control system,it is accomplished by DSP software.Based on constant power loop is strong coupled control loop,it is very difficult to build clear transfer function,the plan leads into fuzzy control tactics and designs fuzzy controller.The simulation results show that this way is feasible and robust.It is easy to implement by digital control also.It offers a new method for motor of weak armature reaction to run in constant power,and this ideal also fits to other motors.
