Abstract

Abstract: To restrain the influences of both dynamics and kinematics disturbances from platform on the control precise of a multitube rocket launcher, a mathematical model of integrated system was established on the basis of permanent magnet synchronous motor (PMSM), and an output regulation method was applied. Because of requirements of exactly known the frequency information of external disturbance and slower convergence of adaptive internal model in normal output regulation problem (ORP), a novel output feedback regulation strategy was designed, including spectrum analysis to estimate the frequency of external disturbance signal, state observation and invariant manifold. Simulation and experiment results demonstrate that the proposed control strategy performs well in depressing the coupling disturbance of rocket platform, and improves the tracking precise and stability of rocket launcher.

Key words: automatic control technology, armament launch theory and technology, rocket laucher, output regulation, invariant manifold
