The paper addresses the position tracking control problem for a stratospheric airship. External disturbances, parameter uncertainties and actuator faults, which are inevitably encountered in practice, can deteriorate the control system performance of an airship. To overcome the challenge, Fault Tolerant Adaptive Sliding Mode Control (FT-ASMC) is presented. FT-ASMC computes the control gain dynamically and ensures the airship tracks the desired position within bounds on states and controls. Simulation results are presented to validate the effectiveness and advantage of the FT-ASMC.

摘要

The paper addresses the position tracking control problem for a stratospheric airship. External disturbances, parameter uncertainties and actuator faults, which are inevitably encountered in practice, can deteriorate the control system performance of an airship. To overcome the challenge, Fault Tolerant Adaptive Sliding Mode Control (FT-ASMC) is presented. FT-ASMC computes the control gain dynamically and ensures the airship tracks the desired position within bounds on states and controls. Simulation results are presented to validate the effectiveness and advantage of the FT-ASMC.
