SUMMARYThe first IEEE International Workshop on Advanced Motion Control held in 1990 pointed out the importance of physical interpretation of motion control. The software servoing technology is now common in machine tools, robotics, and mechatronics. It has been intensively developed for the numerical control (NC) machines. Recently, motion control in an unknown environment will be more and more important. Conventional motion control is not always suitable due to the lack of adaptive capability to the environment. A more sophisticated ability in motion control is necessary for compliant contact with the environment. Acceleration control is the key technology of motion control in an unknown environment. The acceleration control can make a motion system a zero control stiffness system without losing robustness. Furthermore, a realization of multi-degree-of-freedom motion is necessary for future human assistance. Motion for human assistant will require various control stiffness corresponding to the task. The review paper focuses on the modal coordinate system to integrate various control stiffness in the virtual axes. A bilateral teleoperation is a good candidate to consider for the future human assistant motion and integration of decentralized systems. Thus, the paper reviews and discusses the bilateral teleoperation from the control stiffness and the modal control design points of view.

“…The T-type model does not satisfy condition (3) either. As shown later in this paper, five parameters associated with the T-type model are not necessary for the design of vector control systems, such as a slip frequency vector control system [3,13,14] or a spiral vector control system [213].…”

“…In an investigation of model establishment by Tsuji and others, in conjunction with an analysis of the relation between spiral vector control and other vector controls, no attention is paid to conditions (2) or (3) [13]. Although Uchino and others and Iwasaki and colleagues use nonequivalent circuit models, they use the traditional five parameters related to the T-type circuit model and pay no attention to conditions (2) or (3), which thus receive no investigation [14,15].…”

“…Among mathematical models for induction motors, equivalent circuit type models are often used at present, for historical reasons [14]. A set of five electrical parameters in the T-type equivalent circuit, such as stator resistance, stator inductance, mutual inductance, rotor resistance, and rotor inductance, or five other parameters directly related to them, are associated with industrial motors.…”

This paper proposes new mathematical models of an induction motor that generates torque precisely under vector control. The proposed models for the controlled motor have desirable features in respect to preciseness and compactness. They guarantee the same relation between the stator voltage and current signals as does the conventional T-type model consisting of five parameters. The number of parameters forming the new models is reduced to four, such as stator resistance, inverse of rotor time constant, stator inductance, and stator total leakage inductance, or another set of four related uniquely to them. The parameters are uniquely determined by the stator signals, in terms of which all controller parameters of the vector control system can be designed. ©1998 Scripta Technica, Electr Eng Jpn, 126(2): 4855, 1999
