Robust PID Control for Flexible Satellite Considering Dynamics of Thruster Actuator

The purpose of this paper, is to investigate and provide robust PID control for flexible satellite considering thruster actuator dynamics. The flexibility of the satellite causes a change in the dynamics of the entire satellite. During the maneuver, stochastic disturbance torque and system inertia uncertainty are applied to the satellite. The thruster is an actuator used to execute control commands using a PWPF modulator optimized by a genetic metaheuristic algorithm Optimization of thruster and robust PID controller coefficients are other innovations of this paper. By adding angular velocity and control torque constraints, the designed robust control first performs well; And secondly, it is robust to internal and external uncertainties.
