| Abstract |
In this paper, novel auto-tuning method of linear-quadratic regulator (LQR) for DC-DC power converter is presented and experimentally verified. The novelty of proposed approach lies in application of nature-inspired flower pollination algorithm (FPA) to automatic selection of penalty matrices needed for calculation of optimal LQR. The main advantages of the employed optimization algorithm are: reduced number of control parameters, and the ability to implementation of constraint-handling method (CHM). The latter merit ensure limitation of selected state-space and control variables what is crucial for safe operation of the DC-DC power converter. Proposed solution overcomes the main disadvantage of LQR synthesis process related to time-consuming trial-and-error tuning procedure. Simulation and experimental tests illustrate suitable selection of LQR coefficients and proper operation of DC-DC power converter. |
