Based on the theory of differential geometry, the exact FBL and PID controls are applied for the active hydropneumatic suspension of missile launching vehicle. Firstly, the detailed physically based model of hydropneumatic spring is developed and validated by the comparison between experiments and simulation results. Secondly, since the model of active hydropneumatic suspension can be regard as an affine system in general, homeomorphic transformation is used for linearisation of the model. This method guarantees efficiency and validity of the dynamic control system regarding real non-linearities in a large scale of working condition, but not makes the control system complicated. On the other hand, the linearised system derived is ensured to be one-to-one correspondent to the original non-linear system. Therefore, in this paper the fruitful PID control theory is used to direct the design of controller. For investigating the performance of the present non-linear control, numerical simulations are made and results are plotted and shown that the control scheme possesses of higher control precision in comparison with PID control based on TL method. The special requirements for the missile mobile launching are therefore satisfied.
