SWAG合集

The outlined project falls within the realm of Systems Engineering and Mechatronics, particularly focusing on the optimization and safety of electric actuator systems. These systems are integral components in a wide variety of applications, from industrial automation and robotics to automotive systems and aerospace. Given the rapid growth of automation and smart technologies, the relevance of this area today is high. As industries increasingly rely on machines and automation to improve efficiency and reduce costs, ensuring the reliable operation of components like electric actuators becomes vital. This is especially true in critical applications where a failure could result in significant financial loss, environmental damage, or harm to human lives. Moreover, the inclusion of advanced battery management and fault detection mechanisms highlights the intersection of this field with the growing trends in energy efficiency and predictive maintenance. By optimizing the management of battery systems (which are pivotal for actuator operation) and incorporating real-time fault detection, the project touches on key aspects of modern engineering practices: energy sustainability, system reliability, and proactive maintenance. Overall, this project is relevant in the context of the ongoing industrial shift towards greater automation and the need for more sophisticated control and management systems that can adapt to complex operational environments while ensuring safety and efficiency. 

The Project Focus/Aim is to develop and implement an advanced control system for electric actuators, ensuring their safe, efficient, and reliable operation in diverse environments. This involves two main goals:  

1) Optimisation of the Battery Management System (BMS): The aim is to implement an accurate BMS that effectively monitors and manages the health states of the battery powering the actuator. This includes ensuring the State of Charge (SOC), State of Health (SOH), Remaining Useful Life (RUL), and Internal Short Circuit (ISC) are within optimal ranges. The system should also incorporate a Prognostics and Health Management (PHM) system for early detection and prediction of potential battery health issues, enhancing the longevity and reliability of the actuator.  

2) Real-time Isolation and Handling of Actuator Faults: The project aims to design a system capable of identifying and managing faults that may occur during the operation of the actuator. This involves understanding the physics of the motor, the load it is handling, and the role of the servo-controller in the system. The focus is on managing different fault scenarios efficiently, including those during nominal operations, during overloads, and coupling loss faults. By promptly isolating and handling these faults, the system can prevent damage or failure of the actuator, ensuring its ongoing performance and safety. 
 
SWAG合集 is wholly postgraduate, and is famous for its applied research in close collaboration with Industry. At Cranfield, the candidate will be based within the Manufacturing theme at the Centre for Digital Engineering and Manufacturing (CDEM). The Centre hosts cutting-edge simulation and visualisation facilities. The student will have access to high-end computers for simulating the complex nature of maintenance.  
 
The PhD aims to:

1) Enhance Reliability and Longevity: By optimizing the Battery Management System (BMS) and implementing an effective Prognostics and Health Management (PHM) system, the project is expected to significantly enhance the reliability and longevity of electric actuators. Early detection and prediction of potential battery health issues can prevent catastrophic failures, thereby extending the useful life of the actuators.  

2) Improve Safety: The real-time isolation and handling of actuator faults aim to prevent potential damage or failure of the actuator, thereby enhancing its safety. By understanding the physics of the motor, the load, and the servo-controller's role, the project can manage different fault scenarios effectively and maintain the integrity of the actuator even under challenging conditions.  

3) Operational Efficiency: The ability to manage and mitigate faults in real-time means that actuators can maintain optimal performance even when faced with unexpected issues. This ensures continuous and efficient operation, minimizing downtime and maximizing productivity.  

4) Cost Savings: By preventing unexpected failures and extending the life of the actuators, the project can result in significant cost savings. This includes reducing the need for frequent replacements and maintenance, as well as avoiding potential losses due to operational downtime.
