ABSTRACT. The concept of installing smart electric drive, battery unit and control system of a stock car is presented. This work is devoted to AEM control law consisting of auto power plant, providing minimum current consumption for a given traction and speed mode. The practicability of AEM static model usage in the process of synthesis of optimal control of auto power plant with traction electric drives and also choice and substantiation of its basic parameters and characteristics is demonstrated.
Introduction. The complex problem of the scientific substantiation of the basic parameters and characteristics is appeared during designing the new auto power plants. To solve this problem techniques based on the conducting numerical experiments with appropriate mathematical models are used. However, comparative analysis of different design solutions is not possible without algorithms control power plant optimization as whole and individual aggregates that are the parts of it. This work is dedicated to the investigation of AEM control law consisting of auto power plant, providing minimum current consumption for given traction and speed mode. to identifying mathematical models of traction electric drive different vehicles and synthesis of optimal control auto power plants are appeared in recent years. This shows the urgency of the problem. In particular approaches to modeling the power plant of hybrid vehicles, including the AEM as an auxiliary electric drive, and relevant control systems are shown in the articles [1-4]. The problems of AEM mathematical modeling and optimization of the stator current vector are analyzed in the articles [4-8]. The traction electric motor model. However, the task of comparative analysis of different design solutions of auto power plants on the basis of computing experiment raises a number of features in the synthesis models both the object of control and controlling actions. The questions of technical implementation control laws are insignificant. At the same time optimal control vector current on all traction and speed modes under the given constraints and quality criteria of particular importance achieve special value. Herewith the level of complexity of the models ought to provide the ability of the power plant examination in a standard driving cycle of the vehicle. Let us conduct the investigation of different approaches to the modeling of traction electric vehicle based on the optimal control of AEM vector stator current estimate of the magnitude and modeling errors caused by neglecting AEM dynamic properties under control stepped actions. The object of article. To achieve this goal it is necessary to develop the block diagrams of dynamic and static models of electric traction and transmission model car. Comparative analysis of models can be made on time dependences of the main variables obtained for stepped control actions and optimal management of the stator current vector, taking into account the restrictions permissible mode of AEM field.
