Data-Driven PID Control of Cold Gas Micro-Proportion Thruster Module

The data-driven PID control problem of cold gas micro-proportion thruster modules is analyzed. First,a cold gas micro-proportion thruster control system is modeled and analyzed. The general data-driven PID control method and its design process are then introduced. Finally,for the real cold gas micro-proportion thruster,a data-driven PID controller is designed. The analysis of the thruster control system indicates that it is a strong nonlinear system,and the control results show the effectiveness of the data-driven PID control.
