Abstract EN
This work presents an adaptive control that integrates two linear control strategies applied to a step-down converter: Proportional Integral Derivative (PID) and Linear Quadratic Regulator (LQR) controls.
Considering the converter open loop transfer function and using the poles placement technique, the designs of the two controllers are set so that the operating point of the closed loop system presents the same natural frequency.
With poles placement design, the overshoot problems of the LQR controller are avoided.
To achieve the best performance of each controller, a hyperbolic tangent weight function is applied.
The limits of the hyperbolic tangent function are defined based on the system error range.
Simulation results using the Altera DSP Builder software in a MATLAB/SIMULINK environment of the proposed control schemes are presented.
