Simulation validation of a digital F-P control system front-end

In this paper, a new digital F-P filter circuit control system based on differential capacitance principle is proposed. The theoretical analysis and hardware verification of the system are carried out based on FPGA, and the verification results show that the system avoids the problem of poor system time stability of the existing analog circuit control system of F-P filters, and has a very high interference immunity, which provides a new way of thinking for the F-P control system with high stability and no drifting. It provides a new idea for a highly stable and drift-free F-P control system.
