| Shrnutí: | Optimal control in switched reluctance motor drive form the meaning of energy-efficiency and torque ripple reduction is presented in the article. Solutions of control problems, as in the opposite to many others publications - rely on the reference model equations. Model formulas are introduced focusing on its unique aspects - non-linear approximations in the form of cosine and exponential functions. Energy-efficiency of the drive is obtained by applying results of solving analytically desired criterion. Motor phases excitation turn-on and turn-off angles are tested in the range of computed optimal values. The results in the form of introduced energy-efficiency indicators are set together in table. Torque rippling is minimized by applying inversion of model formula for electromagnetic torque. This inversion is possible by introduction of Lambert W operator. Finally, third from the presented control structures introduces torque distribution block (TDB) what gives ability to control torque generation during commutation phase. Algorithms are tested at different torque loads and motor speeds. |
