Although there are different HEV configurations, they are all based on same kinds of components. After introducing the main components HEVs use, we build up a model which can illustrate the basic idea of HEVs. The analysis of the model helps us to reveal the essential problem of HEV power control. The performance of a HEV depends not only on the individual components but also on how the components are coordinated. The power control system must determine operating points for the components during driving to save energy. The proposed power control approach is based on model predictive control and trying to solve the nature problem of HEV power control by an optimization concept, which makes the approach applicable for all kinds of HEVs. A number of different simulations have been executed to prove the feasibility of the approach. By changing some operational weights, the power control system can achieve different performances. / Another key concept adopted in the power control system is based on the premise that future driving load would affect fuel consumption, as well as the operating modes of the vehicle and the driver behavior do. The proposed power control approach incorporates a driving load forecasting algorithm whose role is to assess the driving environment, the driving style of the driver, and the trend of the vehicle using long and short term statistical features of the past drive cycle. This future driving load information is subsequently used to change the operational weights of the power control approach, such as engine efficiency, battery State of Charge (SOC), engine speed, etc. By this way, the power control approach leads to improved the vehicle's overall performance. / One of the major crises that the world is facing today is the problems of energy. With the beneficial effect on the environment and high energy transformation efficiency in hybrid electric vehicle technology, automobile manufacturers have begun to look more seriously into vehicles with alternative power sources. Aimed at solving the more and more serious problems of energy, HEV has been one of the best practical applications for transportation with high fuel economy. / This dissertation proposes a new power control approach for all kinds of hybrid electric vehicles (HEVs). / To obtain better performance, we use particle swarm optimization (PSO) to find optimal weights for different drive loads. Then, by integrating MPC controller and load forecasting algorithm, a realtime HEV power control system, model predictive power control with load forecasting system (MPC-LF), is developed. Experimental results prove the feasibility of the control system. / Wang, Zhancheng. / Adviser: Xu Yangsheng. / Source: Dissertation Abstracts International, Volume: 70-06, Section: B, page: 3631. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2008. / Includes bibliographical references (leaves 132-140). / Electronic reproduction.

The harmonic problem in power systems is gaining more attention as incidences correlated with harmonics increase. Conventional passive filtering techniques for harmonic mitigation have inherent problems, and purely active filters have the disadvantages of higher costs and ratings. Hybrid active filters inherit the efficiency of passive filters and the improved performance of active filters, and thus constitute a viable improved approach for harmonic compensation. To date, there have been several literature works comparing passive and active filters for harmonic mitigation. However, there are currently no comparisons of possible hybrid active filters. This thesis presents an assessment and comparison of hybrid active filters, including their topologies and control algorithms. Three different topologies of hybrid active filters are simulated in PSpice version 9.0 to verify their feasibility for harmonic compensation. From the simulations, all three topologies have better performance over passive filters for harmonic compensation and are insensitive to parameter variations. In addition, the simulated hybrid active filter ratings are lower than can be achieved with purely active filters. A modified "p-q" theory is introduced for control strategy, which is more feasible for extracting harmonic components for distorted load voltages. This thesis concludes with a comprehensive comparison of the hybrid active filter characteristics. / Graduation date: 2001
