摘要
针对非线性时变系统的控制要求,对零开口三通伺服阀控制差动缸系统进行仿真研究。根据三通阀控缸系统的物理模型和框图建立系统数学模型和动态方程,采用适合非线性时变系统控制要求的模糊控制策略,在二维模糊控制器的基础上建立了非线性系统仿真模型,并进行Simulink仿真。仿真结果表明:该模糊控制策略是合适的,能满足系统的控制性能。
The simulation of the three-way valve control cylinder system is studied for the nonlinearity and time-varying in control problem. Mathematical model and dynamic equations are established based on the physical model and frame model of three-way valve control cylinder. Fuzzy logic control strategy is adopted for the time-varying of system, and nonlinear simulation model is established based on two-dimension fuzzy logic controller. The simulation results suggest that the performance of proposed fuzzy logic controller is satisfied.
