【摘要】 建立了基于电子机械制动(EMB)系统的车辆单轴模型。针对制动过程非线性和路面状况复杂多样的特点,提出以滑移率为控制目标,设计了基于等效控制的模糊滑模控制器。利用模糊规则对滑模控制的抖振进行了有效的控制和消除。对该控制器进行了一定初速度下引入模糊逻辑前后的仿真对比和一定初速度下不同路面制动的仿真。结果表明,该控制器具有较好的可行性和有效性。更多还原

【Abstract】 A single axle model of vehicle based on electromechanical brake system was established,in terms of the nonlinear properties of the braking process and the complexity of road conditions,propose slip ratio as the control target,a fuzzy sliding mode controller based on equivalent control is designed,sliding mode control chatter is effectively controlled and eliminated. The simulation results of the controller at some speed are compared before and after the use of fuzzy logic,and simulation of the braking process on different roads at some speed,demonstrating that the controller has a good feasibility and effectiveness.更多还原
