摘　　要：研究步进电机控制精度优化问题。传统的PID控制在控制精度以及调节速度方面,已不能达到理想的效果。针对传统方法的不足,提出引入分数阶控制方法,设计了分数阶PIλDμ控制器来提高步进电机系统的控制精度。首先建立步进电机的数学模型,推导出传递函数,而后分别对该系统设计PID以及分数阶PIλDμ控制器,通过Simulink搭建整个控制系统。参数整定后进行仿真,证明了分数阶PIλDμ控制算法的优越性及可行性。With the widespread use of the stepper motor in industrial, there are new requirements for its control accuracy. The traditional PID can not achieve the desired effect in control accuracy as well as the adjustment time. In this paper, due to the deficiencies of the conventional method, combined with fractional thought of control, fractional PIλDμ controller was designed to improve the accuracy of the stepper motor. First, we created a mathematical model of the stepper motor and derive the transfer function, and established control system structure. Then we used Simulink to carried out the digital simulation of the PID and Fractional PIλDμ algorithm for the system. Finally, we contrasted the control effects and proved the superiority and feasibility of this control algorithm.
