摘要
针对一类单缸液压机,在传统滑模变结构的基础上,设计了基于改进趋近律的滑模变结构控制器,并采用AMESim-MATLAB/Simulink联合仿真模型对其进行了验证。在设计过程中提出引入锻件变形反抗力模块,完善了AMESim-MATLAB/Simulink联合仿真模型,从而可以方便地实现对复杂变形反抗力的数学描述,通过锻件变形反抗力实时反馈通道,可以按照需要灵活设置反抗力的变化,从而真实地再现液压机的工作过程。通过联合仿真接口模块,建立起实时反馈通道,打破了传统仿真模型中只能采用阻尼器来模拟变形反抗力的局限性。最后,对所设计的系统进行了联合仿真,通过对比验证了控制策略及该联合仿真平台的有效性。
For a kind of single cylinder hydraulic press,on the basis of traditional sliding mode variable structure,a sliding mode variable structure controller based on improved reaching law was designed,and the controller was validated by AMESim-MATLAB/Simulink joint simulation model.Then,in the design process,the introduction of deformation resistance module for forgings was proposed,and the AMESim-MATLAB/Simulink joint simulation model was perfected.Therefore,the mathematical description of complex deformation resistance was easily realized.Through the real-time feedback channel of deformation resistance for forgings,the change of resistance was set flexibly according to the need,and the working process of hydraulic press was reappeared truly.Furthermore,the real-time feedback channel was established by the joint simulation interface module to break the limitation that only the dampers were used to simulate the deformation resistance in traditional simulation model.Finally,the joint simulation of the designed system was carried out,and the effectiveness of the control strategy and the joint simulation platform was verified by comparison.
