摘要
气垫船训练模拟器的传输延迟是造成气垫船训练模拟器操作性能下降、影响实时性的主要原因。为减小传输延迟对气垫船训练模拟器的影响,应用改进的lead/lag补偿器提供一个相位超前来补偿由气垫船训练模拟器的传输延迟引起的相位滞后。改进的lead/lag补偿器可应用于非线性、时变的气垫船训练模拟系统,弥补了经典的lead/lag补偿器只能应用于线性、时不变系统的局限性。仿真结果验证了改进的lead/lag补偿器补偿传输延迟的有效性,并且调整改进的lead/lag补偿器的参数可以增强补偿器的补偿能力。
Transport delay in the Hovercraft Training Simulator（HTS） is the main reason of decreasing its performance and affecting its real-time. To decrease the transport delay on the impact of HTS, this paper introduces a modified lead/lad compensator to compensate the phase lag which caused by the transport delay. The modified lead/lag compensator can be applied in non-linear and time-varying HTS systems; and it eliminate the limitations of the traditional lead/lag compensation that it can only be applied in linear, time-invari- ant system. Analysis of simulation results show that it can improve the modified lead/lag compensator effectiveness of delay compensa- tion, and adjusting the coefficients of the modified lead/lag compensator can enhance the compensation capacity of the compensator.
