I. Introduction
Electric vehicles (EVs) have become a significant part of modern transportation, offering numerous advantages, such as zero-emission, low maintenance, and cost-efficiency. The rotational speed of the electric motor in EVs is a crucial parameter that affects the vehicle's performance, range, and safety. Therefore, there is a need for precise and reliable control of EV speed.
Programmable Logic Controllers (PLC) are widely used in industrial automation and have demonstrated their capability in handling complex control tasks. However, their application in EV speed control has not been extensively studied. This study aims to explore the potential of PLCs in controlling the speed of EVs and provides a theoretical framework and experimental setup to validate this approach.
II. Theoretical Framework
A. PLC Overview
PLC is a digital computer designed to automate industrial processes. It consists of a processor, memory, input/output modules, and communication interfaces. PLCs are well-suited for handling complex control tasks due to their high reliability, flexibility, and speed.
B. EV Speed Control
The speed of an EV is controlled by adjusting the voltage and current supplied to the electric motor. The motor's rotational speed is directly proportional to the applied voltage and current. Therefore, by precisely controlling these parameters, the speed of the EV can be effectively managed.
C. PLC-Based EV Speed Control
In this approach, a PLC is connected to the electric motor of the EV through appropriate input/output modules. The PLC receives feedback from sensors monitoring the motor's rotational speed and adjusts the voltage and current supplied to the motor based on predefined control algorithms. This allows for precise and dynamic control of the EV's speed.
III. Experimental Setup
To validate the theoretical framework, an experimental setup was constructed using a PLC-based controller and an EV model. The setup included sensors to monitor the motor's rotational speed, voltage and current sources to supply power to the motor, and a PLC with input/output modules and communication interfaces. The PLC was programmed with control algorithms to adjust the voltage and current based on feedback from the sensors, allowing for dynamic control of the EV's speed.
IV. Results and Discussion
The experimental results showed that the PLC-based controller could effectively control the speed of the EV, achieving a high level of precision and stability. The control algorithms were able to adjust the voltage and current supplied to the motor in response to changes in load and environmental conditions, ensuring optimal performance of the EV. Furthermore, the PLC's communication interfaces allowed for easy integration with other vehicle systems, providing additional functionality and flexibility.
V. Conclusion
This study has demonstrated the feasibility of using PLCs to control the speed of EVs. The theoretical framework and experimental setup have validated the approach, showing that PLCs can effectively manage EV speed with high precision and stability. This provides a new and promising approach for EV speed control, offering numerous advantages, such as increased performance, range, and safety. Future studies can further explore the potential of PLCs in EV speed control, considering various control algorithms and system integrations.
