摘要:

为了提高旋转弹系统的控制品质,采用分数阶控制器进行双通道旋转弹控制系统设计。建立了旋转弹系统控制模型,进行线性化处理和解耦控制,并对解耦后的数学模型设计了分数阶PIλDμ控制器。针对分数阶控制器的参数整定问题,提出一种基于惯性权重的自适应粒子群优化算法,引入惯性权重非线性调整策略来平衡控制全局与局部搜索,从而得到全局最优解。仿真结果表明,该控制模型和控制器的设计合理可行。

Abstract:

In order to improve control quality of the rolling projectiles system, the fractional order controller is applied to control the double-channel rolling projectile. The nonlinear correction rolling projectile system is modeled. The fractional order PIλDμ controller is designed after linearization and decoupling control. In order to solve the parameter tuning problem of the fractional order controller, an adaptive particle swarm optimization algorithm based on inertia weight is proposed. The nonlinear adjustment strategy of inertia weight is introduced to improve convergence accuracy of the algorithm so as to obtain the global optimal solution. Simulation results show that the model and controller are feasible.
