Robust control system design for a brushed direct current motor using LabVIEW simulation loop

Abstract

Abstract. This paper presents the design of a robust control system for a PMDC motor using LabVIEW software. At first, the mathematical equations of the motor were modelled and simulated. Then, a proportional integral controller (PI) was used as a speed controller, and to guarantee the robustness of the system against the disturbances, the PI parameters were tuned by applying a sensitivity analysis. Finally, a proportional gain (P) was used as a position controller to guide the system towards the desired angle. The simulation was performed using LabVIEW Simulation Loop, and the sensitivity analysis was carried using LabVIEW MathScript tool.
