| 摘 要： | 1. INTRODUCTION It is well known that external disturbances exist in almost all practical systems, such as wind or ocean wave forces in active control systems for offshore structures1], harmonic oscillations in flight control systems through wind shear2] , and periodic disturb- ance in the disk drive3]. In recent years, various reliable approaches with regard to the disturbance rejection and cancellation have been well documented in many literatures. Lee et al. 4] proposed the model-ba… |

| Abstract: | Optimal deterministic disturbances rejection control problem for singularly perturbed linear systems is considered. By using the slow-fast decomposition theory of singular perturbation, the existent and unique conditions of the feedforward and feedback composite control (FFCC) laws for both infinite-time and finite-time are proposed, and the design approaches are given. A disturbance observer is introduced to make the FFCC laws realizable physically. Simulation results indicate that the FFCC laws are robust with respect to external disturbances. |
