Abstract

Electro-optical sighting systems are used for surveillance, target acquisition and tracking. The stabilization of the line of sight (LOS) against vehicle-induced disturbances is an essential feature of the electro-optical gimbaled sighting systems, mounted on mobile platforms. Due to factors like host platform dynamics, friction, cable restraint and noise, the pointing and tracking accuracy of the gimbaled system degrades substantially. This work presents control law design for LOS stabilization of a gimbaled electro-optical sighting system, using sliding mode controller (SMC). Other controllers like proportional-integral (PI) controller (conventional frequency domain approach) and linear quadratic gaussian with loop transfer recovery (LQG/LTR) controller (state-space based optimal control) are also compared with SMC for such application. SMC is a non-linear controller that is modified in this work which further reduces the chatter so as to achieve better steady state accuracy. All these controllers meet the stringent requirements of disturbance attenuation and command following.

基于滑模控制的光电瞄准系统视距稳定
光电瞄准系统用于监视、目标捕获和跟踪。针对车辆干扰的瞄准线稳定是安装在移动平台上的光电平衡瞄准系统的基本特征。由于主机平台动力学、摩擦、缆索约束和噪声等因素的影响,平衡系统的指向和跟踪精度大大降低。本文采用滑模控制器(SMC)设计了平衡式光电瞄准系统的LOS稳定控制律。其他控制器如比例积分(PI)控制器(传统频域方法)和线性二次高斯带环路传递恢复(LQG/LTR)控制器(基于状态空间的最优控制)也与SMC进行了比较。SMC是一种非线性控制器,本文对其进行了改进,进一步减少了颤振,从而获得了更好的稳态精度。所有这些控制器都满足干扰衰减和指令跟随的严格要求。
