Abstract

The paper proposes a Birch-inspired optimisation algorithm designed to optimise the PI controller gain and additional feedback coefficients used for robust speed control of a two-mass drive system. The technical issue we considered is torsional oscillation suppression in a two-mass drive system using a robust speed controller. To address this, we used a cascade control structure with additional feedback from torsional torque and its derivative. Since this torque is difficult to measure, a second-order integral disturbance observer was implemented. The integral type of the observer offers lower noise compared to classical derivative solutions. To tune the system, a Birch-inspired Optimization Algorithm was used. The tuned system has been verified through both MATLAB/Simulink environment and experimental verification, demonstrating the robustness and accuracy of the solution.
