Abstract:
This article proposes a multivariable robust controller for the regulation of DC motor angular speed, and for the active current sharing in each parallel DC/DC buck converter. Considering that the parallel DC/DC buck converter is connected in cascade to the armature of the DC motor. Additionally, the controller rejects actively the internal and external disturbances, which is subjected the multivariable linear system. These disturbances are considered time-varying, but they are bounded. The control law is based on differential flatness and active disturbance rejection control with GPI observers. Computer simulations using Matlab/Simulink verified the effectiveness of the proposed controller.
