摘要
针对存在大滞后、时变、非线性特点的液位控制系统在工况大范围变化时传统控制算法控制效果不理想的问题,提出利用模糊控制结合遗传算法的空间寻优能力,对隶属度函数的参数和模糊控制规则的后件进行综合编码优化,利用进化原理寻优来获得最佳的参数进行模糊系统自动设计的方法建立三容水箱控制系统仿真模型,在此模型上验证.仿真结果表明此方法的有效性和实用性.
According to the problem of the existence of large time delay, time-varying, non-linear characteristics of liquid level control system in the condition of changes in a wide range, the traditional control algorithm control is not ideal, a new control method combining fuzzy control combined with the ability of optimization of Genetic Algorithms to auto-design of Fuzzy Systems is proposed, and genetic Algorithms is used to encode and optimize the parameters of membership functions and the consequents of fuzzy rules by evolutionary theory to get the best parameters, and the simulation model of three-tank liquid level control system is established based on the simulating result verifies. The method is effective and practical.
