Doctor Do's major contribution to systems and control is his research on control of systems subject to nonholonomic constraints such as underactuated mechanical systems including surface ships, underwater vehicles, mobile robots and aircraft, and control of networks of multiple vehicles. He has made significant contribution to the understanding dynamics and developing novel methods to design controllers for these systems. For nonholonomic systems with strong nonlinear drifts and unknown parameters, he developed a method called input-to-state scaling to design a global asymptotic stabilizer. For land, air and ocean vehicles, he proposed various solutions to the problems of stabilization, trajectory-tracking and path-following. He introduced a methodology called dynamics from a different view, which results in several ways to derive coordinate transformations to overcome difficulties in controlling these vehicles. His involvement with Western Australia ship- and air-vehicle-building industries (Austal, Shipdynamics, Entecho) has enriched his industrial activities and practical experience. Currently, he is a senior lecturer in the School of Mechanical Engineering at the University of Western Australia. He teaches Advanced Control Engineering and Navigation and Marine Control Systems units.
Professor Jie Pan is the Director of the Centre for Acoustics, Dynamics and Vibration at the School of Mechanical Engineering, University of Western Australia. His contribution to the field of applied control was initially in active control of noise and structural vibration. Since 1999, he and his research team have worked on the control of ocean vessel vibration and motion, where he played a role not just as a team leader and project organiser, but also provided physical insight into the understanding of system dynamics and their role in controller design. He also established several fundamental and industrial research projects on active control of marine vessels' vibration, and active vibration control of marine risers, from which several outstanding PhD, Masters and final-year theses were generated and some problems of ride control systems in the Western Australian ship-building industry were solved. Many results described in this monograph are the products or by-products of those projects and thesis work. Professor Pan's teaching covers classical control, advanced control and mechatronics, vibration and signal processing, and acoustical engineering.
