Modeling and Simulation of Pressure Control for Stratospheric Platform Airship

An atmospheric model is presented for super pressure control of airships under different movement states. By analyzing the changes of each state variable during the longitudinal movements under different control strategies, both longitudinal movement model and control model for the airship are established. During the simulations of the airship´s ascent, float and descent with super pressure control, different strategies are studied respectively. In order to prove the correctness of the models and the feasibilities of the super pressure control strategies under different movement state, a simulation system under VC6.0 with both manual control mode and automatic control mode is established, which is capable to describe the whole process of the airship´s ascent, float and descent with super pressure control. An illustrative example is given to show that the models are effective and the super pressure control strategies are valid and feasible
