| 摘 要： | 针对车辆主动悬架模糊PID控制设计,提出了一种利用遗传算法整定模糊PID增益系数的方法。基于二自由度的1/4车辆模型,根据模糊控制原理和PID控制方法,设计了主动悬架的模糊PID控制器。利用具有全局寻优能力的遗传算法,以悬架二次型性能指标为目标函数,采用适应性比例法确定选择概率,整定了模糊PID的增益系数。优化结果表明,整定后的模糊PID控制主动悬架相对被动悬架综合性能良好,说明了提出的方法是有效的,对模糊PID控制设计具有重要的参考价值。

| Abstract: | A method of setting gain coefficients of fuzzy PID based on genetic algorithm is proposed for designing a vehicle active suspension system controlled by fuzzy PID.Taking a one-quarter vehicle with two degree freedom as an example,a fuzzy-PID controller of active suspension is established according to fuzzy control theory and PID control method.Then the gain coefficients of fuzzy PID are set by applying genetic algorithm with global search ability assuming suspension quadratic performance index as target fun... |
