Resumo: |
This work involves the application of robust controls D-LQI and D-pole placement via LMIs in a high-gain boost with three states switching cell. This converter consists of a modern topology derived the classic boost converter . This boost converter is considered a step-up converter, which a range of 4254V voltage input to 400V voltage output. The proposed boost converter is reduced to equivalent model and is modeled at space state avarage, in which is observed that the matrix D =6 0, being then a modeling that presents a peculiarity according to literature, thus the control solution is more complex. The control strategies applied use mathematical procedures called Linear Matrix Inequalities (LMIs), which can be solved by convex optimization or positive semidefinite procedures (SDP). The mathematical tools used to solve the LMIs this work are Yalmip and SeDuMi , which are inserted in MATLAB . Further analyzes the uncertainties present in the process, as well as the robustness of closed loop model. The simulation results are obtained via MATLAB and PSIM and analyzes made regarding these results, besides the analysis of experimental results and conclusion of study, in addition to proposals for future work. The Appendix shows the installation procedures and use correct solvers based on the equations described in LMI theory. |
