| 摘 要： | 针对由电机惯性造成的电动执行器不能精确定位的问题,介绍了一种新的电动执行器控制算法——贴近算法,并对基于该算法的电动执行器进行了仿真分析。不同于传统的电动执行器,基于贴近算法的电动执行器不需要任何制动装置就能有效地利用电机的惯性准确定位。详细描述了贴近算法,利用Matlab编程实现了该算法,最后对电动执行器进行仿真试验。仿真结果验证了贴近算法的可行性、有效性及局限性。

| Abstract: | Aimed at the problem that electric actuator cannot fix position precisely due to the inertia of motor,a novel control algorithm-proximity algorithm as well as the simulation analysis of electric actuator based on this algorithm was introduced.Different from traditional electric actuator,the electric actuator based on proximity algorithm utilized the inertia of motor effectively to fix position precisely without any brake apparatus.Proximity algorithm was presented in detail and realized based on Matlab.The feasibility,effectiveness and limitation of proximity algorithm are validated by the simulation results. |
