摘要由于受系统功耗和空间的限制，为满足小型化、结构简单的需求，常规弹药激光引信采用新型的双向驱动单发单收大视场探测方案。而电机是实现双向驱动的旋转扫描系统的重要组成部分，因而为在高速动态情况下实现激光引信的精确探测，必须对其进行稳速平衡控制。25823

Title Stable speed balancing control for laser circumferential probe rotation scanning
Abstract
Due to the limitation of space and power consumption of the system, A new type of double - way - driving single - Single - receiving large - field detection scheme is used for conventional ammunition Laser Fuze to meet the requirements of miniaturization and simple structure. The motor is an important part of the bidirectional drive rotation scanning system. In order to realize the accurate detection of laser fuze in high speed and dynamic laser fuze, the steady speed balance control must be carried on.
In this paper, by consulting relevant literature, the working principle, types, application development of motor are systematically understood, and the motor control principles are simply understood, laying the foundation for future research. In the first chapter, the background and significance of the research is introduced. In the second chapter, the mathematical modeling of the motor is attempted. In the third chapter, the basic principle and method of several motor control are briefly introduced, the development and direction of the motor control are known,and a relatively maturely developed speed - current double closed-loop proportional-integral (PI) speed control system is ultimately chosen. In the fourth chapter, based on the change of input parameters, adjusting the PID parameters, in the cases of the process of starting and sudden load operation, the MATLAB is used to simulate the behavior of motor.
