Abstract

Abstract

The vibration of the pump and pipeline of marine power plant is transmitted to the main body through the base or the support, which results in serious troubles. The controller is the core of the active vibration control (AVC) system. Aiming at the shortcomings of the traditional controller, an active vibration controller based on shared memory technology is proposed. Both analog-to-digital (A/D) conversion acquisition module and digital-to-analog (D/A) output module contain micro-control units (MCU). Field programmable gate array (FPGA), digital signal processing (DSP) and MCU in real time read data from or write data to the shared memory which is structured in superblocks and data blocks. At the same time, the maximum sampling frequency and the system delay error of the controller are verified, and the error channel identification test is carried out on the simulation bench. The results show that the controller can meet the requirements of low frequency line spectrum control, improve the data transmission efficiency, and ensure the real-time performance of the system.
