An embedded controller based on DSP and ARM dual-core processor is designed in this paper to explore the miniaturization technology of the measurement and control units for smart piezoelectric structure. The system construction, the core devices, system hardware and software design, system functional parameters and the development process are illustrated in detail. Combining the adaptive filter feed-forward control algorithm, active vibration control experiment is carried out for the vibration suppression of smart piezoelectric structure, based on the constructed model structure and experiment platform. The experimental results show that the designed embedded controller is feasible and effective, and beneficial results are got for miniaturization of the measurement and control system for piezoelectric smart structures.
