AB  - This article first investigates the dynamic coverage control problem for the 
      multiple stratospheric airships (MSAs) system considering its practical 
      application scenarios. A dynamic coverage control framework is put forward, in 
      which the MSA system can be guided and controlled to fully cover the observation 
      target region. Once a specific target is detected, the coverage target can be 
      switched. First, the location information of the monitored target is predicted by 
      an autoregressive model against processing delay. Second, the coverage control 
      scheme consists of two layers: a novel potential field-based virtual control law 
      to generate the desired velocity and angular velocity and an adaptive tracking 
      controller to track them. In the virtual control law, a dynamic artificial 
      potential field is introduced to adapt to the dynamic scenarios. In the tracking 
      controller, which is combined with the adaptive control technique and the 
      saturation compensator theory, the external disturbances and input saturation are 
      addressed. Third, the event-triggered mechanism is designed to reduce the control 
      frequency to prolong the actuator life. The simulation results are given to 
      substantiate the capability of the proposed dynamic coverage control framework.
