“…The acceleration Wy of the endtip is kept in lower level while the desired mechanical impedance and feedback gain are the same with those in Simulation 2. From this result, the effectiveness of the desired trajectory given in Equation (4) is verified. This desired trajectory is also employed in the following simulations.…”

A docking mechanism and its control scheme are discussed for high performance autonomous docking systems. A problem is to achieve soft docking of the system to a satellite approaching the docking mechanism with relative velocity and to absorb the shock of collision. To solve the problem an intelligent adaptive structure is examined to use as the docking mechanism. Control strategy for the docking mechanism is discussed and a PD-impedance control, i.e., impedance control combined with PD-control, is proposed. The docking mechanism is controlled along an appropriate trajectory by using the PD-impedance control and the soft docking is achieved. Feasibility and advantage of the proposed scheme are verified by numerical simulations.

“…The studies and/or developments of the intelligent or adaptive structure have been actively made as an attempt to use the unique function in ISAS, JPL [2] and MIT [3]. Although there are some studies on physical properties [4][5][6], no systematic approaches have been made on control problems.…”

“…Both dynamic characteristics and vibration control of variable geometry truss (VGT) structures with length-variable members and high damping truss joints were extensively studied in the first phase [for instance, 39,40]. The techniques for vibration suppression used in the space structures are essentially the same as in earthbound structures, although the large space structures are dynamically characterized by very low natural frequencies of lower modes.…”
