【摘要】 分析了模糊控制器的量化因子和比例因子对系统性能的影响,并针对基本模糊控制器存在不能消除稳态误差以及无法同时获得较好的动态性能和稳态性能的缺点,提出一种新型带可调因子的模糊控制器的设计方案。并以工业过程普遍存在的带滞后的二阶对象为例设计这种模糊控制器,仿真结果表明该模糊控制器能获得较常规模糊控制器优良的控制效果,因而更具有实用价值。更多还原

【Abstract】 The effects of quantitative factor and proportionality factor on the performance of a system with fuzzy controller are discussed.To address the problems in the basic fuzzy controllers that the steady-state errors cannot be eliminated,and that the good dynamic characteristics and steady state properties cannot be simultaneously obtained,this paper proposes a design of a new fuzzy controller with adjustable factor.This kind of fuzzy contro ller is designed,taking the second ordelr subject w ith delays as an example that cominouly existed in the indust-rial processes.Simulation results show that this controller is better than the conventional one as far as the control performance is concerned.So it has applied value.更多还原
