Due to the coexistence of continuity and discreteness, energy management of a multi-mode power split hybrid electric vehicle (HEV) can be considered a typical hybrid system. Therefore, the hybrid system theory is applied to investigate the optimum energy distribution strategy of a power split multi-mode HEV. In order to obtain a unified description of the continuous/discrete dynamics, including both the steady power distribution process and mode switching behaviors, mixed logical dynamical (MLD) modeling is adopted to build the control-oriented model. Moreover, linear piecewise affine (PWA) technology is applied to deal with nonlinear characteristics in MLD modeling. The MLD model is finally obtained through a high level modeling language, i.e. HYSDEL. Based on the MLD model, hybrid model predictive control (HMPC) strategy is proposed, where a mixed integer quadratic programming (MIQP) problem is constructed for optimum power distribution. Simulation studies under different driving cycles demonstrate that the proposed control strategy can have a superior control effect as compared with the rule-based control strategy.

At the beginning of the work on the effects of global warming and climate change in the international area, there are efforts to reduce exhaust emissions. Because fossil fuel is depleting and exhaust emission gases emitted to the atmosphere are rising rapidly, energy efficiency is on the agenda in transportation. Therefore, automotive developers and scientists have undertaken new research in the automotive sector. Hybrid electric vehicle technology is one of the important studies that these researchers continue. In the hybrid electric vehicle technology, the hybrid engine is aimed to give the best results in terms of exhaust emission, fuel consumption and maintenance costs compared to other internal combustion engines, and at the same time the hybrid engine is aimed to perform better than other internal combustion engines. General information about the hybrid electric vehicle technology as one of the new and alternative technologies in these study is provided. In addition, information was given about exhaust emission, emission standards and fuel consumption. Comparisons were made between the hybrid engine and other internal combustion engines.

Przyczyny błędów wartości skoku silników reluktancyjnych i silników hybrydowych z osiowym podmagnesowaniem wirnika leżą zarówno po stronie niedokładności wykonania elementów magnetowodu – wirnika i stojana, jak też symetrii uzwojeń oraz symetrii działania komutatora. Również w innych typach silników skokowych, tarczowych czy tzw. pazurowych, przyczyny błędów skoku są podobne. Dodatkowo w silniku z wirnikiem w postaci magnesów trwałych sposób ich namagnesowania również wpływa na błędy skoku. Zagadnienie to zostanie wyjaśnione przy opisie silników wymienionych typów.
