摘要

摘要: 粒子群优化算法（PSO，Particle Swarm Optimization）在空空导弹μ综合控制器参数优化中易出现早熟现象而无法获得全局最优解.针对此问题，提出一种动态加速常数的粒子群优化算法（CPSO，Constant Particle Swarm Optimization）.改进算法通过对加速常数的指数形式变化，在寻优前期扩大搜索范围，在后期提高收敛效率，从而避免了寻优过程中的早熟现象.仿真结果表明，改进的CPSO优化算法具有更强的全局搜索能力，设计出的μ综合控制器具有更优的性能，满足给定的性能指标和自动设计指标，节省了大量设计时间，具有工程应用价值.

Abstract: Particle swarm optimization (PSO) algorithm is prone to premature convergence in the control parameter optimization of air-to-air missile μ-synthesis controller, which makes the global optimal solution inaccessible. Aiming at this situation, dynamic acceleration constant particle swarm optimization (CPSO) algorithm was proposed. This improved algorithm, through changing the index form of the acceleration constant, expanded the searching range in the beginning phase of optimization, improved the efficiency of convergence in its latter phase, and finally the premature phenomena was avoided. The simulation results reveal that the improved version of exponential CPSO algorithm is of great significance in engineering applications. It has a better ability in global searching. μ-synthesis controller based on this algorithm maintains optimal performance, which meets the given performance indicators and automatic design specifications and saves much design time.
