- Considering the typical nonlinear characteristics of srm drive system which make the constant parameters of traditional controller unable to adapt to the random disturbance parameters in a large scale , the fuzzy control is introduced to improve its performance . a fuzzy self - tuning controller is designed , which can adjust parameters automatically and improve its static and dynamic performance
鉴于开关磁阻电动机调速系统显著非线性造成固定参数在常规控制方式下不能很好适应工况大范围变化的问题，引入了模糊控制来改善其性能，设计了模糊自校正控制器，实现了参数的在线优化调整，提高了系统的静、动态性能。 - Meanwhile , the paper analysis shortage of the methods commonly used heating insulating oil , investigate principles of traditional pid control and fuzzy control , integrats the advantage of two control algorithms , makes use of fuzzy + pid control algorithm to control insulating oil temperature , and has designed fuzzy + pid controller . through matlab simulation , validates that wavelet hard threshold vale de - noise method can effectively reduce the impact of random disturbance
同时,论文分析了常用加热绝缘油方法的不足,在研究传统pid控制和模糊控制原理基础上,综合两种控制算法的优点,在绝缘油介损测量系统中,提出采用模糊+ pid控制算法对绝缘油温度进行控制,并实现了模糊+ pid控制器的设计。 - But in analyzing the dynamic characteristics of rolling mill , we find that the system exists nonlinear uncertainty and slow time - variation , which are caused by nonlinear mode and random disturbance . this leads to the approximation of the practical system of the model and parameter and it is difficult to construct the accurate mathematical model . therefore , the routine controlling method is n ' t used any longer
然而，在分析轧机的动态特性中发现，由于位置内环的模型中存在非线性元件，系统受到过多外界扰动的影响致使系统中存在非线性、不确定因素及慢时变参数的现象，推导出的模型结构和参数只是实际系统的一个粗糟近似，难以建立精确的数学模型，此时，常规控制方法已不再适用。 - Besides , the converters have unmodeled dynamics . so the traditional controller for hvdc based on the classical control theory can not meet the requirements in practice . although , pi controllers are widely used in the hvdc systems , they have high sensitive responses to random disturbances , low robust performance , and can not solve some problems in power systems , such as unmodeled dynamics , nonlinear uncertainties
直流输电线路中的换流器具有很强的非线性，系统的运行工况随时都会发生改变，系统扰动发生的地点、类型及严重程度具有随机性；此外，换流器还含有未建模动态部分，这些因素使得基于直流输电系统准静态模型的常规控制器设计方法常常不能很好地满足系统的实际要求。 - The research indicated that , if the secondary combustion chamber was looked on as a controlled object , with the adjusting valve as a input , the pressure and the temperature of a selected point on the inside wall of the combustion chamber as outputs , then such controlled system would be a strongly non - linear , time varying system with number of random disturbances , which resulted in huge difficulty to build an analyzed mathematics model for the spray burning of the liquid fuel , so that classic control methods were all invalid
研究表明，若将rbcc发动机的二次燃烧室视为一个控制对象，同时以燃烧室内壁面取定点处的压强、温度和调节阀的开度为输入输出变量，则该系统将是输入?输出特性非线性很强、随机干扰严重的复杂时变系统。这导致建立燃油喷雾燃烧具体模型的很大困难，从而宣告了经典控制方案的失效。
