Electrorheological (ER) fluids is one of the most favorite actuator materials used in smart materials and structures due to its fast, reversible, controllable and continuous change of rheological properties. In this paper, an optimal electric field control technique for ER fluids in squeeze mode with broadband Vibration source is presented. The proposed controllers are equivalent approaches based on the 2-norm (H2) principle for minimizing broadband Vibration spectrum energy. Both of the theoretical derivation and experimental investigation are conducted in present study. In the theoretical derivation, an optimal damping coefficient of fundamental ER squeeze mode and numerical simulation from model are presented. In the experimental work, the relation of damping coefficients and electric fields are obtained from preliminary experiments. The optimal controller is designed with an optimal damping coefficient for minimize Vibration spectrum energy and implemented on an ER squeeze mode test platform. The experimental results indicate that the proposed controller is effective in suppressing broadband Vibration and yield minimal transmissibility spectrum.
