Hybrid Power Plant

The problem of control of a hybrid power plant of a car consisting of an internal combustion engine, a synchronous electric motor with permanent magnets and a synchronous generator is considered. The formation of the control effect is carried out taking into account the connection of the above objects with each other with the help of planetary transmission. The mathematical models of the three listed engines are nonlinear with several control channels. In addition, the principle of the hybrid power plant requires the simultaneous operation of these engines and, accordingly, the construction of the necessary interrelated control actions. To synthesize the laws of vector control of a hybrid power plant, the method of analytical construction of aggregated regulators (ADAR) is used. Within the framework of this method, it is possible to work with a complete nonlinear control object model. Unlike the traditional approach of constructing a separate stabilizing control for each control channel, this method uses co-control over all variables to transfer the object to the desired state. In this case,for a number of variants of control algorithms, the communication between the control channels is carried out not indirectly, through the control object, but directly formed in the regulator. In addition, the control law takes into account unknown external disturbances, which were compensated using the principle of integral adaptation. In this paper, one of the modes of operation of a hybrid power plant is shown during the acceleration of the car. First, only the electric motor works, as the car accelerates, the internal combustion engine is connected, and at high speeds only the internal combustion engine works. This mode of operation of the hybrid power plant allows using both engines in the most convenient range of angular speeds, which leads to an economical fuel consumption and a charge of the storage batteries. In addition, the second electric motor operates in the generator mode and transfers a part of the mechanical moment to recharge the batteries.

This article discusses the problematic issues of the study of the characteristics of wheeled plug-in hybrid electric vehicles (PHEVs) in accordance with the requirements of the Ukrainian classification of goods of foreign economic activity. Existing types of hybrid power plants are considered. We consider the problems that are solved by experts in automotive industry in the study of wheeled vehicles with hybrid power plants. Problems of determining the type of hybrid power plant of a wheeled vehicle, the principle of its operation, and, consequently, the influence of this on the determination of the code according to the UKT ZED (Ukrainian Classification of Goods for Foreign Economic Activity) are considered. Currently, in expert practice, there is no single approach in carrying out research to determine which characteristics the wheeled vehicle meets according to the Ukrainian Classifier of Goods of Foreign Economic Activity. In this article the main types and types of hybrid power units, the principles of their operation and the effect on the definition of the code under the UKT ZED are given. In relation to wheeled vehicles to one or another code under the UKT ZED it is necessary to determine the scheme of the operation of the hybrid power plant. In this case, hybrid power units operating on a parallel and serially parallel circuit should be classified in the code of code 8703 2 "Other vehicles with spark ignition internal combustion engine and crankshaft coupling" or 8703 3 "Other vehicles from an internal combustion engine with compression ignition (diesel or semi-diesel), and hybrid power plants that operate in a sequential scheme to the code number 8703 90 90 00 "other" as not falling under the requirements of the other the position of the booty on the principle of its work.

This article looks at some comparative statistics on the development and use of electric vehicles (hereinafter referred to as EM) as an example of sales and future sales forecasts for EM in countries that focus on environmental conservation. Examples of financial investments already underway and to be made in the near future by the largest automakers in the development and distribution of EM in the world are given. Steps are taken to improve the environmental situation in countries (for example, the prohibition of entry into the city center), the scientific and applied problem of improving the energy efficiency and environmental safety of the operation of wheeled vehicles (hereinafter referred to as the CTE). The basic and more widespread schemes of conversion of the internal combustion engine car (hereinafter -ICE) to the electric motor car (by replacing the gasoline or diesel electric motor), as well as the main requirements that must be observed for the safe use and operation of the electric vehicle.

To avoid unnecessary power loss during switching between the various power sources of a composite electric vehicle while achieving smooth operation, this study focuses on the development and dynamic simulation analysis of a control system for the power of a parallel composite vehicle. This system includes a power integration and distribution mechanism, which enables the two power sources of the internal combustion engine and electric motor to operate independently or in coordination to meet the different power-output requirements. The integration of the electric motor and battery-charging engine reduces the system complexity. To verify the working efficiency of the energy control strategy for the power system, the NEDC2000 cycle is used for the vehicle driving test, a fuzzy logic controller is established using Matlab/Simulink, and the speed and torque analysis of the components related to power system performance are conducted. Through a dynamic simulation, it is revealed that this fuzzy logic controller can adjust the two power sources (the motor and internal combustion engine) appropriately. The internal combustion engine can be maintained in the optimal operating region with low, medium, and high driving speeds.

The 19Th Century

This article focuses on the engineering credit that should be given to the bicycle designs and its hand in today’s technological innovations. Design improvements during the first 90 years of the bicycle’s history provided much of the initial technology that was extended to modern motorized forms of transportation. More important than the bicycle’s effect on the close of the 19th century was its influence on the 20th. The most common hybrid vehicle of the future may not be the now familiar four-wheel automobile combining an internal combustion engine and electric motor, but the electric bicycle that can be powered either by a rider’s muscles or energy stored in a battery. A development like that would be almost full circle. The only difference between that future and the first safety bicycle would be that electric power was harnessed along the way.

Introduction. The use of an electromechanical transmission in the design of a tracked vehicle allows an increase in the complex indicator of mobility, an increase in the range, fuel efficiency, maximum speed, a decrease in acceleration time, etc. The improvement of these indicators is achieved mainly due to the different performance characteristics of the internal combustion engine and the energy characteristics of electrical machines. The latter fact makes it possible to ensure the operation of the power plant of the tracked vehicle in such a way as to avoid unfavorable operating modes of both the internal combustion engine and the elements of the electromechanical transmission (a generator, a traction electric motor, an energy storage) from the point of view of energy efficiency, and to realize the high efficiency of the entire system.Research methods. To improve the mobility and implement a rational strategy for electromechanical transmission control, it is necessary to have an idea of the effective modes of operation of the main elements of the power plant. As a way to solve this problem it is proposed to study the energy characteristics of the main elements of an electromechanical transmission using the developed mathematical model for various modes of movement of a tracked vehicle.Results. Modeling the motion of a tracked vehicle with an electromechanical transmission makes it possible, in addition to determining the transmission parameters, to formulate preliminary requirements for its characteristics.Discussion and conclusion. To solve these problems, it is necessary to simulate the process of movement of a tracked vehicle, taking into account the initial data that are adequate to real operating conditions.
