| 摘 要： | 针对常规模糊控制器控制精度低的问题，提出了一种提高模糊控制器控制精度的方法。文章首先分析了常规模糊控制器存在的稳态控制精度差的原因，然后针对这个问题提出一种提高模糊控制器控制精度的方案并给出了它的设计方法。最后给出这种改进的模糊控制器的仿真试验结果，并和常规模糊控制器进行了比较。仿真试验结果表明，这种改进的模糊控制器具有消除系统稳态误差的作用，提高了模糊控制器的控制精度，而且保持了模糊控制器非线性的控制特性，易于实现，有一定的实用价值。

| Abstract: | To counter the problem of lower controlling precision of fuzzy controller, this paper puts forward a method to improve controlling precision of fuzzy controller. First, the paper analyses the reason of lower controlling precision of conventional fuzzy controller, then puts forward a method to solve this problem and gives its design method, finally gives the simulating results of the improved fuzzy controller and compares with conventional fuzzy controller. The simulating results prove that the improved fuzzy controller can really eliminate stable state error and improve the controlling precision of fuzzy controller. The improved fuzzy controller retains the nonlinear controlling property of conventional fuzzy controller, its design is simple and its realization is easy, it has certain practical application value. |
