定量反馈理论在双液压作动器同步控制器设计中应用

Application of Quantitative Feedback Theory on Synchronization Controller Design of Dual Actuators Driven System

以定量反馈理论为基础,对双液压作动器同步拖动系统的同步控制器设计进行了研究。即以双作动器的系统模板为研究对象,使用定量反馈理论方法和多数入多输出稳定性条件设计两作动器的前向控制器、交叉耦合控制器和前馈控制器。通过实验结果,验证了所设计控制器的有效性。

Investigates the cross-coupled synchronization controller design on the basis of quantitative feedback theory （QFT）. During the design process, frequency characteristic sets of two motors are used as the system plant. Then, forward controller and coupled controller are designed through QFT （quantitative feedback theory） SISO （ single-input single-output ） and MIMO （ multiple-input multiple-output ） design methods. Additionally, feedforward controller is also utilized. Experiment results validate effects of the designed controllers.
