The demands for very accurate engine control are currently increasing rapidly. Governments everywhere are concerned with the amount of pollution that is being emitted into the biosphere. With good reasons. Doctors report of an increased number of asthma and other lung related diseases.

说明：   本书内容深入浅出、图文并茂、理论与实训紧密结合，各章之间既相互联系又相对独立，读者可根据需要选择阅读。本书每章内容都包括两部分，一部分为理论讲解，以丰富多样的实例作为支撑；另一部分为与理论部分配套的MATLAB仿真实训，本部分与理论部分前后呼应，同时密切结合生产实践。 (The Guide book illustrations, theory and practical training closely, both among the various chapters of interconnected and relatively independent, readers may be selected to read. Content of each chapter the book consists of two parts, the theoretical explanation, to a variety of examples as support the other part is matching with the theoretical part of the MATLAB simulation training, this section with the theoretical part of the previous ones, while keeping a close with the production practice.)
