Abstract:
Doktorska disertacija prikazuje primer zelo robustne izvedbe tokovne regulacije BLAC motorja, izvedene po principu nelinearnega vodenja. Zaradi zahteve po zelo visoki dinamiki, in pretežni uporabi logičnih operacij, bo sistem izveden na FPGA električnem vezju. Osnova bo dvonivojska histerezna tokovna regulacija, ki jo odlikujejo robustnost, visoka dinamika in enostavna izvedba, kot tudi visoko in nekontrolirano število preklopov, ki predstavlja največjo pomanjkljivost te metode. Izvedba dogodkovnega vodenja ohranja vse odlike histerezne regulacije, hkrati pa močno zmanjša število preklopov. Takšen način tokovne regulacije zagotavlja sinusno komutacijo izvedeno s tabelo na FPGA, ki jo definira estimirana vrednost napetostnega sektorja. Dogodkovni princip tokovne regulacije zagotavlja strogo konvergenco po določilih Lyapunove funkcije. Dogodkovno vodenje omogoča tudi prediktivno vodenje, osnovano na kriterijski funkciji kvadratičnega pogreška.

Title:
EVENT DRIVEN CONTROL OF BLAC MOTOR
Abstract:
This thesis presents non-linear principle of very robust current control implementation of BLAC motor. High dynamic and dominant use of logic operations leads to implement such system on FPGA. This thesis is based on two-level hysteresis current controller that is characterized by robustness, high dynamic and very simple implementation. The main disadvantage of this controller is uncontrolled switching number. Event driven implementation keeps all advantages of hysteresis controller and also avoid problem with uncontrolled high switching number. This method provides a sinusoidal commutation made with look-up table on FPGA that is defined by the value of estimated voltage sector. Event driven current control provides strict convergence under the terms of Lyapunov functions, and also allows predictive control based on the objective function of a quadratic current.
