Abstract

This paper proposes a novel switch-mode power stage architecture for actuator array. When the number of actuator is large, the associated power amplifier becomes costly and bulky if each actuator is controlled by an independent amplifier. The proposed architecture allows sharing of the power amplifier among actuators, and thereby reducing the number of switching devices. The architecture is mapped into the graph theorem and the acceptable actuation states are analyzed. The switching method is controlled by an MIMO optimal feedback quantization, which is designed to minimize a weighted measure of the quantization distortion. Simulation results are provided to illustrate the effectiveness of the proposed scheme.
