Research on Several Techniques of Four Axis Rudder Control System

In this paper,determined a rudder control strategy in the analysis of the basic principle of rudder control.It presented a hardware implementation according to the control core of single FPGA and power drive components of SA305,and gave the overall system architecture block diagram after studying the key technologies of axis for ultra-compact digital rudder control system.It focused on the implementations of PI controller,multi-channel AD converter serial read and write control based on FPGA,E2PROM interface control and the cut-off protection of current.The results show that this rudder control system has good control performance.
