Abstract
The Lyapunov-based decentralized adaptive control system is presented because the piezo-electric steering system is complex dynamics and can not know status of the controlled plant. The decentralized control technology is adopted. The non-linear error and parameter drift error are introduced to make the dynamic model more exact and the adaptive feedback and forward control terms are added to improve the control adaptability and tracking precision. The adaptive parameters are decided by the Lyapunov function in order to assure the system is stable. The control project in this paper are proved to be valid and reliable according to the simulation results.
