Abstract Aiming at the problem that the all-digital driving technology flow tube is difficult to start vibration, five kinds of starting methods such as analog to digital start-up, random wave start-up, sine wave start-up, sweep frequency square wave start-up, and positive-negative step alternate start-up are reviewed. Aiming at the problem that the amplitude, frequency and phase of driving signal are difficult to adjust, the solution is proposed. For the implementation platform of all-digital drive technology, two solutions are summarized: a single-core all-digital drive based on DSP and a dual-core all-digital drive based on DSP+FPGA. Among them, the single-core all-digital driving based on DSP has low cost and is easy to promote, and the dual-core all-digital driving based on DSP+FPGA has higher precision.
