英文摘要： As one of main weapons, Multiple Launch Rocket System (MLRS) has been paid great and wide attention by every powerful country, which can be regarded as complex multibody systems with uncertain parameters articulated by the rigid bodies, flexible bodies, and control elements with various ways. Dynamics control principle, design method and experiment of multibody MLRS are the key to get high firing precision of MLRS. In order to solve the problem that dynamics calculations is not enough quick to achieve the dynamics control design method of the complex multibody MLRS with uncertain parameters, combining with Monte Carlo simulation, a stochastic controlled transfer matrix method for multibody MLRS will be developed, which can avoid establishing the global dynamics equations of the system and the overall transfer equation automatically by handwrite or by computer. The rapid computation and rapid control design of dynamics with uncertain parameters will be realized. The dynamics control performance of the MLRS will be improved. In order to solve the problem that control law for the complex multibody MLRS with uncertain parameters is to complex to achieve good control effect in engineering, a stochastic independent modal space control strategy combining with transfer matrix method for multibody system is designed, and the primary experiment will be studied, and the active vibration control of complex multibody MLRS with uncertain parameters is realized. The basis problem for improving the firing precision of MLRS will be solved by this research, and a new method to realize the dynamics control design of MLRS will be provided.
