Positioning control of vibration systems such as flexible structures is one of the most fundamental technologies for mechanical structures. Different from feed forward control based methods, the use of LQ optimal regulator realizes the feedback control of vibrating parts of a controlled object. However, if the standard LQ optimal regulator is applied to long distance positioning problems, it requires...
This paper presents a LC-based sub-harmonic injection-locked frequency quadrupler which multiplies a 15 GHz input to 60 GHz quadrature(I/Q) output signals. The proposed quadrupler can use a lower-frequency PLL for incident signal than doublers and triplers, which is very advantageous to implement a wide-tuning and low-phase-noise PLL. The proposed frequency quadrupler is implemented by using a 65...
Many power-assist systems for industrial uses possess simple power-assisting function only. The authors studied on the positioning method of a cart using a smooth switching from the servo access control for the conveyance function to the force sensorless impedance control (FSLIC) for the power-assisting function. The nonstationary optimal control method and the nonstationary impedance control law...
The objectives in this paper are to develop a method for safety-preservation oriented reaching monitoring (SORM) and to demonstrate its effectiveness for realizing a safe and smooth control mode switching. For more effective manufacturing activities, smooth control mode switching of a power assist device ldquoSkill-Assistrdquo from hands-off to hands-on is expected to enhance the productive efficiency...
