Vibration control of piezoelectric cantilever beam based on cyclic mutation immune clone algorithm

In this paper, the mathematical vibration model and the control transfer function model of a cantilever beam are established, and then a new immune clone algorithm with cycle mutation is designed. The algorithm can avoid a lot of cumbersome work about precise calculation of system parameters, improve the control of active vibration suppression of the cantilever beam, and realize learning control. Finally, the experimental system of piezoelectric intelligent cantilever beam is constructed. According to comparative experiments, the algorithm which is designed in this paper has capabilities of faster convergence speed, better control effect, and automatic adjustment of the control parameters through self-learning; it is also convenient in practice.
