【摘要】 基于逆系统控制思想,提出一种支持向量机(SVM)直接逆控制与PID控制相结合的复合控制策略。采用支持向量机离线训练的方法实现了对系统逆模型的辨识,并将辨识出的逆模型作为控制器,与被控对象串联,构成一个伪线性系统,在此基础上,采用增量式PID控制器(IPIDC)进行补偿式控制。仿真实验表明,该复合控制方案不仅能使系统具有良好的动态响应性能,而且具有较强的鲁棒性和抗干扰能力。更多还原

【Abstract】 Based on the thought of inverse system control,a composite strategy was proposed,which combines direct inverse control based on support vector machine(SVM)with PID control.The inverse model was identified by an off-line training method,lately working as a controller and connected with the plant in series,which forms a pseudo linear system.On the basis of this,an incremental PID controller was applied as a compensatory control.Simulation results demonstrate that the proposed composite control system has a good dynamic response performance,as well as good robustness and resistance to disturbance of system.更多还原
