摘要
针对目前中小功率永磁同步电机控制器存在通用性不强,性价比不理想及控制精度欠缺的不足,提出一种基于Stm32的永磁同步电机矢量变频控制器,应用于中小功率永磁同步电机。控制器采用了磁场定向算法,分析了异步电机与同步电机的控制数字系统控制环路上的异同,实现了一套代码能同时适用两种电机的控制,并能在有无传感器方式下运行。适合用户不同的应用场合与需求,高性价比的Stm32微处理器使系统精度提高且成本得以下降,符合技术先进性与经济实用性要求。通过理论分析与实验验证,证明了该策略的可行性。
In order to solve the problemsof low versatile, non-ideal in cost-effectand low control accuracy in present PMSM controller, a new frequency conversion controller basing on Stm32 is put into apply. The controller adopts the magnetic field orientation algorithm, analyzes the similarities and differences between the control loop of the control system of asynchronous motor and synchronous motor, realizes a set of codes that can be applied to two kinds of motors at the same time, and can operate in both sensor and sensorlessmode. It is suitable for different applications and needs of users. The Stm32 micro controller with high performance price ratio improves the system accuracy and costs, which meets the requirements of technology advancement and economic practicality. The feasibility of the strategy is proved by theoretical analysis and experimental verification.
