报告题目：Practical Applications of Precision Motion Control to Industrial Mechatronic Systems

报告摘要：

“Motion Control” is one of practical academic disciplines on the basis of control theories, and has been extensively applied to actual “Mechatronic Systems” in various industrial fields. For example, fast-response and high-precision motion control should be indispensable in a wide variety of high performance mechatronic systems including micro and/or nano scale motion, such as data storage devices, machine tools, manufacturing tools for electronics components, and industrial robots, from the standpoints of high productivity, high quality of products, and total cost reduction. In those applications, the required specifications in the motion performance, e.g. response/settling time, trajectory/settling accuracy, etc., should be sufficiently achieved. In addition, the robustness against disturbances and/or uncertainties, the mechanical vibration suppression, and the adaptation capability against variations in mechanisms should be essential properties to be provided in the performance.

This series of lectures, therefore, presents how the motion control can be applied to a wide variety of mechatronic systems to achieve the required motion performance, from the experiential viewpoints of education/training, research, and development activities through the strong collaborations with industries. Examples of the R/D activities for the actual industrial products, including the required performance as well as promising control techniques, can be presented to easily understand the “basics and applications of precision motion control” for newly enrolled master and Ph.D students after learning the basis of control theories. The course consists of 3 lectures as follows:
Lecture #1: Introduction: Basics and applications of precision motion control to high precision mechatronics

1. Background of motion control and mechatronic systems

2. Motion control applications in industry

3. Collaborative research programs with industry

4. R/D approaches toward advanced motion control: Fundamental 2-DOF control framework

5. Practical issues for mechatronics and practical techniques toward precision motion control

Lecture #2: Fast and precision positioning/tracking approach: Friction modeling and compensation

1. Fundamental knowledge on “Friction” in motion control
- Friction as a disturbance in mechanisms
- Examples of motion control performance deteriorations by friction effects
- Practical issues and approaches in motion control

2. 2-DoF control-based fast and precise positioning with friction modeling and compensation
- Rolling friction modeling and compensation
- Disturbance observer with initial value compensation

Lecture #3: Practical applications of optimization algorithms to motion controller design

1. Auto-tuning of motion controller by Genetic Algorithms: Free parameters for mathematical models and compensators

2. Applications of learning and heuristic approaches to motion controller design

3. Applications of LMI-Based Design to Command Shaping in Motion Control

4. Coordinate Design Between FF/FB for Fast and Precise Positioning
