| 摘 要： | 提出了基于PWM控制气液联控位置系统的建模方法,应用非线性平均方法建立了PWM气压伺服系统的数学模型,不仅解决了开关的不连续性问题,还把原来不连续的非仿射输入形式变成一个等效具有可控规范型的非线性仿射输入形式。然后运用滑动模态变结构理论中的经典非线性设计方法,设计了三阶滑模面变结构控制器。对固定阻尼式气液联控系统进行了位置控制仿真实验。实验结果表明,滑模变结构控制使得系统快速性能比较好。

| Abstract: | A new modelling method of the pneumatic hydraulic combination control(PHCC) servo system was presented,which was driven by Pulse-Width-Modulation(PWM).The model of PWM pneumatic systems was built by nonlinear state averaging method,which overcame discontinuity of on/off valves,and changed discontinuous non-affine form into a control canonical nonlinear affine form.A three-rank sliding controller was designed according to traditional nonlinear design method of sliding mode variable structure theory.The simul... |
