Intelligent Control Strategies for Nonlinear Systems with Faults

为了保护公众的健康和安全，对机械和电气系统的可靠控制和诊断有很大的需求。该研究计划旨在开发智能控制器和策略，可用于许多不同的工程系统，包括汽车，飞机，机器人和无人机系统，仅举几例。该计划的长期研究目标是为系统提供技术，使其能够成功地预测故障的发生，并在故障事件发生之前采取适当的控制措施。换句话说，为系统提供某种形式的认知。这为社会（安全）和经济（降低维护成本、减少灾难性事件和减少停机时间）提供了许多好处。拟议的活动对于增进该领域的知识和理解是重要的。此外，这项工作将对许多行业产生积极影响，包括：汽车、航空航天、国防、制造业和空间系统。

In order to protect the public health and safety, there is substantial need for the reliable control and diagnosis of mechanical and electrical systems. This research program aims to develop intelligent controllers and strategies that can be used by a number of different engineering systems, including cars, planes, robots, and unmanned aerial systems, to name a few. A long-term research goal of this program is to provide techniques for a system to enable it to successfully predict the occurrence of faults and take appropriate control actions prior to the fault event. In other words, provide a system with some form of cognition. This offers a number of benefits to society (safety) as well as the economy (reduced maintenance costs, fewer catastrophic events, and less downtime). The proposed activities are important to the advancement of knowledge and understanding within the field. In addition, this work will have a positive impact in a number of industries, including: automotive, aerospace, defense, manufacturing, and space systems. My research group studies intelligent control and estimation methods. We seek to advance the use of machine learning (artificial neural networks) and Bayesian (probability-based) techniques on engineering control and estimation problems. Inherent to intelligence is the ability to remember the past (memory) and predict the future (estimation) based on a knowledge base (built through human training or system interactions) and the external environment (measurements and senses). Sometimes referred to as cognitive', intelligent controllers are able to learn (adapt) over time and are able to predict and anticipate the future environment. Intelligent systems are important to protect the public health and safety. In addition to technical advancements, my research group trains highly-qualified personnel who help meet Canada's demand for engineers and will contribute to its economic success.
