This is the pilot study of adopting system dynamics model and method to demonstrate the organizational inertia of knowledge-intensive business services in perspective of dynamic evolution. This study aims to establish the causal feedback constructs and the corresponding dynamic models. It reveals that the motivation of enlarging the dimensions of organizational inertia from the structural inertia...
GPC (generalized predictive control) is widely used in the control of plant with inertia and delay. This paper proposes feed-forward and feedback GPC in the control of MIMO system. The coupling is treated as knowable exterior disturbance and considered during the designing process of GPC controllers. With structure analysis, the new controller is equivalent to feed-forward and feedback control system...
The present paper discusses how human adjusts the mechanical impedance of upper limb in order to perform the reaching task under unstable environments. We identify both the arm stiffness and inertia during horizontal movements using the direct drive manipulator. It is then shown that the stiffness and inertia of the upper limb are cooperatively adjusted such that the dynamic range is kept higher in...
In motion control, the major sources of uncertainties are friction, stiffness, inertia and disturbances. These uncertainties should be taken into account by any high performance robust motion controller. Position and speed controllers for two-mass systems with different performances, ranges of applicability and of different complexity need to be used. The objective of the paper is to propose a motion...
