| 摘 要： | 电子节气门是典型的非线性机构,应用普通滑模控制算法时具有明显的抖振现象,故提出了基于非线性补偿的电子节气门滑模控制。通过设计观测器来观测并补偿电子节气门系统中的非线性因素,从而减小滑模切换项的增益,达到降低切换频率的目的;使用李雅普诺夫方法分析了系统的稳定性。仿真和试验结果表明,该算法能有效地降低系统抖振,满足控制要求。

| Abstract: | The electronic throttle was a typical nonlinear mechanism,which had obvious chattering phenomenon when the sliding mode control was applied.Through observing and compensating nonlinear factors of electronic throttle system,the switching gain was reduced and hence the switching frequency was lower.The stability of system was analyzed with Lyapunov method.The simulation and experiment results show that the method can effectively reduce the chattering of system and meet the control requirements. |
