摘　　要：单变量泵驱动双变量马达速度同步控制系统是一个具有耦合、非线性特点的多输入多输出系统,也是工程机械液压底盘模拟实验台研制中的技术难点。提出了一种基于流量均衡控制与压力、速度之和反馈相结合的控制策略。仿真验证表明,采用该方案控制下的单泵双马达系统即使在经受不同载荷干扰时也能保持系统稳定,并可快速同步到设定的速度。该方法无需解耦,简单易行,适用于工程车辆同步控制。The system of one hydraulic displacement pump driving two hydraulic displacement motors to achieve speed synchronization is a multiple inputs and multiple outputs one with coupling and nonlinear characteristics. It is also a key job in researching on engineering vehicles hydraulic chassis simulation experimental device. A control strategy that the flow rate equilibrium was combined with pressure and speed feedback, was put forward. By simulation,it indicates that this system is stable and can get good synchronization results even suffering the different load disturbances. This method is simple and easy to be used without decoupling. It is suitable for speed synchronization control of engineering vehicles.
