摘　　要：针对柴油机怠速控制系统中控制对象的大滞后性、惯性、非线性等特点,提出一种基于T-S模型的模糊PID控制器的设计方法。它的前件采用模糊推理的方法将基于语言变量的专家经验转化为T-S模型的模糊规则,后件则采用PID的控制形式,这样设计可以充分借鉴常规PID控制器参数调整的各种成熟经验,使模糊控制规则的制定和参数的调整更简单易行,且物理意义明确。大滞后、非线性控制对象的现场试验表明,T-S模型模糊控制器有着很强的适应性和鲁棒性,明显改善了系统的动静态性能。该控制器设计简单,与Mamdani系统相比在形式上更加紧凑和易于计算,可以很方便地采用自适应的思想来创建系统模型,同时也可以广泛应用在其它需要闭环控制的实际工程项目中,因而具有一定的研究价值。For the characteristics of large time delay and inertial of diesel＇s idle control system,a method of fuzzy PID controller is proposed based on T-S model. The controller adopts the fuzzy rules of T-S model that converted from expert experience and the output form of traditional PID controller,which can make the traditional PID controller ＇s mature experience about parameters adjustment be fully absorbed and establishment of fuzzy control rules be more simple,the physical meaning also become clearer. Through the simulation of large lag objects,it is proved that the fuzzy controller has strong adaptability and robustness,obviously improves the dynamic and static performances of the system. The controller has a simple structure,and it is more compact and easier to calculate in form compared with Mamdani system. In addition,the T-S system model can be easily created by using self-adapting thinking and widely used in other actual engineering projects that need keep constant pressure,so it is worth to research.
