摘要
文章中电控罗经采用数字伺服控制方案来取代传统的模拟伺服控制方案,将微处理机引入控制系统。设计了基于PID控制的静基座和摇摆基座下电控罗经的控制算法,运用Simulink进行建模和仿真,并通过实际转台测试实验得出,所设计的数字伺服控制电控罗经在摇摆实验环境下,稳定时间为1.8h,罗经的稳态误差为0.5°,满足设计预期指标和国际标准要求。该电控罗经可以克服系统调试困难的缺点,具有实现复杂计算和现代化控制算法的能力。
The electromagnet control gyrocompass uses digital servo control to replace the traditional analog servo control scheme. The microprocessor is introduced to control system. The control algorithm of the electromagnet control gyrocompass based on the static base and swing base controlled by PID is designed. Simulink is utilized for modeling and simulation. The actual turntable test experiment showed the digital servo control electromagnet control gyrocompass’ s settling time is 1.8 h and its steady-state error is 0.5° in the swing test environment, which meet the design specifications and international standards. The electromagnet control gyrocompass can overcome the shortcomings of the system difficult to debug, with the ability of complex calculations and modern control algorithms.
