The Design of a Reaction Flywheel Speed Control System Based on ADRC

The reaction flywheel is a crucial operational component within satellite’s attitude control system. Enhancing the performance of speed system holds significant importance for satellite control. In this paper, an active disturbance rejection (ADRC) approach introduced to mitigate impact uncertain disturbances on precision. designed as ADRC controller due current challenge measuring unknown accurately in To derive rotor’s observation value and estimated total value, sampled data rotor position torque signal are fed into extended state observer. compensated feedforward control, which could significantly effects various nonlinear disturbances. paper initially establishes rationale behind through theoretical analysis, followed by analysis differences PID MATLAB/SIMULINK. Simulation results demonstrate evident advantages over terms command tracking capability suppression ability. Subsequently, program implemented circuit, experiments conducted contrast suppression. Importantly, experimental outcomes align with simulation results.
