CONTROL SYSTEMS SIMPLIFIED
The advent of digital computers and the availability of ever cheaper and faster microprocessors has brought a tremendous amount of control system applications to the automotive industry in the last two decades. From engine and transmission systems, to virtually all chassis subsystems (brakes, suspensions, and steering), some level of computer control is present. Control systems theory is also being applied to comfort systems such as climate control and safety systems such as cruise control or collision mitigation systems. This seminar begins by introducing the highly mathematical field of control systems focusing on what the classical control system tools do and how they can be applied to automotive systems. Dynamic systems, time/frequency responses, and stability margins are presented in an easy to understand format. Utilizing Matlab ® and Simulink ® , you will learn how simple computer models are generated. Other fundamental techniques in control design such as PID and lead-lag compensators will be presented as well as the basics of embedded control systems. During this interactive seminar, you will utilize case studies to develop a simple control design for a closed loop system. And, with the aid of a simple positioning control experiment, you will learn the major components and issues found in many automotive control applications today. LEARNING OBJECTIVES By attending this seminar, you will be able to: • Determine performance characteristics of open and closed loop systems such as time and frequency responses and stability margins • Analyze compromises and select the best compromised solution between stability and closed loop performance metrics • Model simple physical systems in MatLab ® /Simulink ® environment • Analyze and design simple compensators in MatLab/Simulink environment • Evaluate issues associated with digital control systems including effects of sampling time, word length, and throughput • Explain the functions of various components found in today’s automotive embedded control systems including ECU I/O section, software/algorithm, power electronics, and sensors and actuators • Communicate with control systems designers more effectively in terms of technical issues as well as toolsets, and functional needs
“Great seminar to acquire practical understanding of control systems. The material was delivered in such a way that even an engineer out of school for 20 years could understand!”
