Preface
Special section on mechatronic systems The special section on Mechatronic Systems includes 10 papers, which were among 141 invited and contributed papers presented at the 2nd IFAC Conference on Mechatronic Systems held on December 9–11, 2002 at the University of California, Berkeley. Invitation for inclusion in this section was extended to 13 papers based on the inputs from the members of the international program committee and sessions chairs; one invitation was declined and two papers were judged to be not suitable for the journal after review. The first paper in this section, ‘‘Automotive Mecha. tronics’’ by Dr. P. Schoner, was the opening plenary talk at the Conference. It presents the motivation, technical challenges and future of mechatronics along with representative mechatronic solutions in the automotive industry. The automotive/ground vehicle applications were a strong part of the Conference; a paper on semiactive suspension by Fischer et al. and another on hydraulic clutch control by Monatanari et al. represent the area of automotive applications. ‘‘Assessment of Active Stability Control Strategies for a High Speed Bogies’’ by Pearson et al. introduces how control theoretic methodologies have been applied to the area of rail transportation in the context of mechatronics. A paper by Lee and Tsao on material testing systems presents how advanced control methodologies such as repetitive control and back-stepping may enhance the performance of modern mechanical systems. The Hard Disk Drives (HDD) industry strives to achieve higher storage densities at a reduced cost, and there are vigorous research activities in the mechatronics community to respond to this need. A paper by Marcassa and Oboe on HDD presents such an activity. ‘‘Modeling a 5-DOF Haptic Interface for Isotropic Force Control’’ by Lee et al. presents a design of new haptic interfaces; it is also an excellent example of applying the multivariable control theory to modeling and controller design of multi-degree of freedom mechatronic systems. The conference program included sessions on actuators and mechatronic components. The following two papers

belong to this category. A paper by Lee and Sosseh presents characterization of a spherical motor, a unique new mechatronic component. A paper by Garagic and Srinivassan presents friction compensation for a strut by applying adaptive control. Finally, a paper by Hintz et al. presents an identification method for physical parameters and nonlinear characteristics of mechanical systems with a known structure. These 10 papers are collectively an excellent summary of how control methodologies help design and operation of mechatronic systems. The IFAC Technical Committee on Mechatronic Systems (MIS) sponsored the Berkeley mechatronic conference. The Committee was established recently in response to the ever growing importance of mechatronics in various industries such as automotive, biomedical, information storage devices and aerospace. Industrial products are increasingly sophisticated and complex, and industry must respond to the needs of market and society with high-quality products in a timely manner. Mechatronic approaches pursue the synergy achieved through the integration of mechanical, electrical, and information technologies in the design, manufacture and operation of industrial products and processes; synergies may be in terms of performance, physical dimension, cost, power efficiency, time for development, dealing with complexity, and so on. I would like to take this opportunity to thank the members of the International Program Committee for soliciting, reviewing and compiling papers to form an exciting technical program at the conference. For other papers presented at the conference, please refer to the Proceedings published by Elsevier.
