Abstract :
SFLAC (state feedback and load acceleration control) is proposed for vibration suppression and disturbance rejection control of n-inertia system. An n-inertia system is a model of a steel rolling mill, flexible arm, large scale space structure, etc., and its control will be an important problem in the future motion control. The main idea of SFLAC is to control the load acceleration which can be estimated by the state observer including the disturbance estimation. A simple PI speed controllers and SFLAC based on the reduction models using 2 and 3 inertia moments are designed. The effectiveness of SFLAC is demonstrated showing some simulation results.<>
