LOS稳定系统H_∞优化设计

The ADRC Design of Vehicular Steady Sighting System

基于H∞混合灵敏度优化控制对坦克装甲战车瞄准线双轴稳定系统进行了设计。针对双轴稳定瞄准线系统高精度、宽频带控制要求,采用H∞范数作为性能指标,结合经典控制经验,讨论了混合灵敏度设计的加权函数选择问题,给出了具体选取原则。仿真结果证明了控制器设计的有效性。

Based on H∞ hybrid sensitivity optimization control, a biax LOS stabilized system for the tank and armored fighting vehicle is designed in this paper. Taking H∞ norm as specification, the system is designed through choosing weight function. Selections of weight functions in the hybrid sensitivity design are discussed in detail, the detailed selection rules are given in accordance with requirements of high accuracy and wide frequency band for the biax stabilized LOS system and experiences on the classical control. The simulation results prove that the design method has its directive function in the design of servo control system.
