摘　　要：液压系统按照控制原理可以分为泵控系统和阀控系统两大类。扫雷器的液压系统主要是阀控,阀控系统动态特性良好、控制精度高,但存在节流损失和溢流损失,故效率低。采用串联式泵阀协调控制系统可以综合泵控系统和阀控系统的优势,提高能源利用效率、系统响应速度、控制精确度和稳定性,并提供更多的功能和灵活性。首先,建立了某扫雷器电液伺服系统的数学模型,然后将泵阀协调控制系统中的泵控部分和阀控部分分别设计控制策略,泵控部分主要是辅助控制,采用减小节流压降的控制策略。阀控部分为主要控制部分,为保持其控制性能,采用GABP-ADRC控制策略,并利用AMEsim和Simulink软件对该改进自抗扰控制器进行联合仿真验证。Hydraulic systems can be divided into two categories based on control principles:pump control systems and valve control systems.The hydraulic system of the mine sweeper is mainly valve controlled,with good dynamic characteristics and high control accuracy.However,there are throttling losses and overflow losses,resulting in low efficiency.The use of a series pump valve coordinated control system can integrate the advantages of pump control system and valve control system,improve energy utilization efficiency,system response speed,control accuracy and stability,and provide more functions and flexibility.Firstly,a mathematical model of the electro-hydraulic servo system of a certain mine sweeper was established.Then,control strategies were designed for the pump control and valve control parts of the pump valve coordinated control system,respectively.The pump control part is mainly auxiliary control,using a control strategy to reduce throttling pressure drop.The valve control part is the main control part.To maintain its control performance,the GABP-ADRC control strategy is adopted,and the improved self disturbance rejection controller is jointly simulated and verified using AMEsim and Simulink software.
