摘要
为了提高光电稳定跟踪平台伺服性能, 针对车载光电稳定平台的扰动特点, 依据自抗扰控制算法的分离特性, 提出一种含有积分补偿项的自抗扰控制伺服系统, 系统对指令信号安排过渡过程, 即采用最速控制方案。实际摇摆测试结果表明:设计的自抗扰控制伺服系统既保证了车载光电稳定平台稳定误差为0.129 mil(1σ), 又提高了平台的自动跟踪性能, 是一种可应用在稳定跟踪平台系统中的理想控制器。
Abstract
Aiming at the disturbance characteristics of vehicle photoelectric stabilization platform and the separation characteristics of active disturbance rejection control(ADRC) algorithm, an active disturbance rejection control system was provided with integral compensation for improving the servo performance of vehicle photoelectricity stabilization tracking system. Practice swing testing shows that the ADRC method ensures the stabilization precision of platform is 0.129 mil(1σ), and improves the automatic tracking performance. It is an excellent controller for stabilization platform tracking circuits.
