摘要
针对多框架陀螺稳定平台中谐振频率较低和摇摆台摇摆换向时跟踪误差曲线上出现尖峰问 题,提出了一种串联平方滞后超前校正环节和非线性加速度补偿措施,设计了平台速度稳定环。在摇摆台按幅值为o5,周期为6s的正弦规律运动条件下,稳定精度为8.3,满足指标要求,表明该速度稳定环在实际中是很有效的。
In accordance with low resonance frequency in a multi-frame gyroscope-stabilized platform and spikes appeared in tracking error curve when swing platform changes swing directions, a velocity-stabilized loop with serial square lag and lead correction network and nonlinear acceleration compensation measure is designed. The stabilization accuracy is 3.8 double prime when the platform swing amplitude is 5° and sine moving period is 6 s. This fulfills the demands in technical specifications and shows that the velocity-stabilized loop is very effective in the practical applications.
