Design of model reference adaptive control using a lattice notch filter to suppress unsatisfied vibration

The conventional feedback controller cannot perform well especially in presence of elastic behavior of flexible systems and variation in the character of disturbances, resulting in the reduction on the stability of the control system. This paper deals with designing a control strategy based on ‘model reference adaptive approach ’applied to appraise a single vibration mode of the system. This approach makes of a model reference adaptive lattice notch filter which has been implemented on the system in the case of recursive form to the elimination of the unsatisfied vibrating frequency. The performances of the proposed control algorithms are evaluated by means of simulation on MATLAB and Simulink.
