摘要 电液执行器(EHA)中的传感器或执行器故障,会导致系统不稳定,存在安全隐患。为了解决这些问题,提出并研发了一种用于EHA的容错控制补偿技术。建立其数学模型,利用PID控制器进行位置跟踪控制,通过重构的未知输入观测器实现对干扰和传感器故障的诊断和误差补偿;利用容错控制补偿技术,可以提高EHA运行的可靠性和稳定性,确保控制器的稳定性及其跟踪性能。通过数值模拟和实验,证明了所研发的容错控制补偿技术的有效性。 Malfunctions of sensors or actuators in electro-hydraulic actuators can cause system instability and pose safety hazards.To adress these problems,a fault-tolerant control compensation technique for EHA is proposed and developed.The mathematical model is established,the position tracking control is carried out by PID controller,and the interference and sensor fault diagnosis and error compensation are realized by reconstructed unknown input observer.Fault tolerant control compensation technology can improve the reliability and stability of EHA operation,ensure the stability of the controller and its tracking performance.The effectiveness of the fault-tolerant control compensation technique is proved by numerical simulation and experiment.
