导弹飞行仿真液压转台控制系统参数整定策略

基于模拟、数字混合控制技术的导弹飞行仿真液压转台的控制系统包含一系列需要进行参数整定的环节.本文从工程实用的角度提出了循序渐进的参数整定策略,并分别详细论述了驱动电路、模拟速度控制回路、数字位置控制回路的参数整定方法.实践表明,本文提出的参数整定策略,首先保证了调试过程的安全,并且使控制系统的性能指标达到了预定的要求,即静态位置精度达到0.001,°最小平稳速度达到0.001°/s,内、中、外轴的90°相移带宽分别达到22Hz、15Hz和13Hz,可以满足导弹飞行仿真试验的需要.

The Strategy of Control Parameters Adjustment for Missile Flight Simulation Turntable

There are several sections that need to be adjusted in an analog-digital combined control system of a missile flight simulation turntable.A set of parameter adjusting strategy in proper sequence for this control system is proposed in this paper from the view point of engineering application.The practical trimming methods for the driver circuit,analog control loop and digital control loop are described in detail.The final results show that,the strategy proposed by this paper is viable.The safety in the adjusting process of the control system is ensured.The fine index with positioning precision of 0.001,minimal speed of 0.001/s and 90 phase shift bandwidth of 22Hz,15Hz and 13Hz for inner,middle and outer axis respectively is achieved,which will satisfy the demands of missile flight simulation.
