Clutch Displacement Servo Control in Gear-Shifting Process of Electric Vehicles Based on Two-speed DCT

In this paper, a robust active fault tolerant control (AFTC) scheme is proposed for induction motor drives (IMD) via input-output linearization control (IOLC) and nonlinear observer. In order to estimate the states and to reconstruct the faults, two different observers are used; a Luenberger observer (LO) and an extended kalman filter (EKF). Further we introduce feedback linearization strategy by choosing the output function as the rotor speed and flux square. To provide a direct comparison between these FTCs schemes, the performance is evaluated using the control of IMD under failures, variable speed, and variable parameters, finally the obtained results show that the proposed controller with the proposed observers provides a good trajectory tracking, and these schemes are robust with respect to faults, parameter variations, and external load disturbances for induction motor drive system.

Electric vehicles (EVs)/Hybrid electric vehicles (HEVs) are implemented with Hybrid Energy Storage System (HESS) to obtain the effective results. HESS has been framed by combining battery with ultracapacitor (UC). Here the battery is used to supply the average power whereas UC can meet the transient power requirement of an electric vehicle. UC always assists the battery during peak power requirements and starting of the motor can also be done. The problem associated with HESS powered vehicle is switching between battery and UC depending upon vehicle road conditions. The main aim of this work is to design a controller for proper switching of energy sources in HESS. With four individual math function, one controller has been designed based on the speed of the electric motor, named as Math Function Based (MFB) controller, further, this has been integrated with ANN as well as Fuzzy logic made two new hybrid controllers. After that two-hybrid controllers have been implemented for the electric motor, thereafter comparative analysis has been made between them and suggested one good controller based on different comparative factors. The two-hybrid controllers have been implemented in four modes and results are discussed in the simulation results and discussion section.

“…Inspite of various advantages of PLC and SCADA, no work is reported on remote monitoring of AC system using PLC and SCADA except [17][18][19], in which a very few brief results were discussed. The results presented in this paper are in detail and give in-depth idea of working of AC system in remote and local mode.…”

Air conditioners have become an important need in industrial and domestic places. On the other hand industrial automation tools provide a wide range of applications in control and monitoring of mechanical, power, automobile, telecommunication systems etc. Programmable Logic Controller (PLC) and Supervisory Control and Data Acquisition (SCADA) can be easily used as automation tool in HVAC industries. In this work we present the monitoring and controlling of AC system employed for more prominent work space using PLC and SCADA. PLC is used at the remote end as hardware to supervise and control the required air conditioning space. The ladder logic developed for programming PLC is provided which can also be implemented in monitoring and controlling of multiple AC systems in remote and local mode to operate either automatically or manually. SCADA is used to operate remotely by developing Graphical User Interface (GUI) using CIMPLICITY software. With all the features, this designed system is capable of efficient handling of the resources such as the compressor, blower, condenser etc. With all the levels of safety and durability, it maintains the temperature and control humidity levels within the official work place and also looks after the health of the compressor.
