摘要: 传统的输出反馈H∞优化控制设计比较复杂,由于控制器的阶数要远远高于实际系统的阶数,在实际工业控制过程中不容易实现。从次优控制的角度出发,利用量子粒子群算法解决特定结构的H∞混合灵敏度优化控制设计。对带有超前/滞后环节控制器的SISO锁相闭环摩托速度系统和PI 型控制器的MIMO超级机动F18/harv 战斗机系统使用量子粒子群算法进行了分析,并和GA算法进行了比较。实验仿真显示了量子粒子群算法的有效性。

Abstract: The conventional output feedback designs of H∞ optimal control are very complicated and not easily implemented
for practical industrial application because the order of the controller is much higher than that of the plant.In this paper,
a Quantum-behaved Particle Swarm Optimization(QPSO) for the design of a structure specified H∞ optimal problem is proposed
from sub-optimal perspective.This method is very advantageous for practical control systems.Two examples involving a
SISO phase-locked-loop motor speed system with lead/lag type controller and a MIMO super maneuverable F18/HARV fighter
aircraft with a PI-type controller are given to illustrate the design procedure and exhibit the effectiveness of the proposed
method via a comparison study with an existing GA approach.
