串联式混合动力电动汽车发动机转速新型PID控制

在混合动力电动汽车中发动机转速的优化控制是降低油耗、减少排放的关键。而发动机转速系统是一个复杂的变参数非线性系统，且很难获得其准确数学模型。本文在常规的PID控制的基础上引入单神经元自适应控制，提出了发动机转速控制的优化目标。台架试验证明控制器能够较好地实现对发动机转速控制。

A New PID Control Method for Engine Speed of Hybrid Electric Vehicles

The optimized control system for engine speed of a hybrid electric vehicle is the key to keeping as low as possible fuel consumption and vehicle emission. This system is complex with non linear property and therefore is difficult to get a precise mathematical model for it. This paper introduces the single neural cell adaptive control based on the traditional PID controller and puts the optimization goal of the engine speed control system. Tests prove that the method can achieve effective engine speed control.
