摘要/Abstract

摘要： 为了提高重型汽车电控机械式自动变速器起步控制的平顺性，在对接合点前后加速度变化的分析基础上．提出了采用变结构串级双环控制维持发动机转速恒定的起步控制算法．针对离合器操纵系统的非线性特性，加速度环采用单神经元自适应PID（Proportional Integral Differential）控制算法来解决非线性控制问题．实验结果表明采用该算法可有效抑制接合点前后的加速度，从而提高起步过程的性能．

Abstract: In order to enhance the smoothly character of the startup process of the heavy truck, a startup control algorithm is proposed based on the analysis of the acceleration fluctuation before and after the lock point, which adopts variable structure cascade double loop control to keep the rotating speed of the engine constant. Considering the nonlinear characteristics of the clutch operating system, the neuron adaptive PID control algorithm is adopted in the acceleration loop to solve the problem of nonlinear control. The experiment results show that acceleration fluctuation before and after the lock point can be restrained by using this algorithm, then the performance of the launch process is improved.
