Title: Radio telephone system
Inventor: NISHIDA MORITSUGU
IPC: H04Q7/22
Filed: 1993-04-05
Abstract: PURPOSE:To reduce the disconnection of talking due to inter-zone requiring. CONSTITUTION:The system is provided with a position registration section 114 registering a slave station in its talking available area and a resident time recording section 115 recording the resident time of the slave set of the area, and selects a 2nd slave set whose resident time is longest in the area among slave sets using channels of a 2nd zone. Then the talking of the 1st slave set moving from the 1st zone to the 2nd zone is continued by replacing the channel of the 1st zone used by the 1st slave set with the channel of the 2nd zone used by the 2nd slave set. Thus, even when all channels of a zone of a moving destination are busy, the possibility of consecutive talking is increased.

Title: Method and device for controlling double inertia resonance system
Inventor: KANG JUN HYOK
IPC: G05B5/01
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of vibrations by controlling a drive means based on the difference between the estimated load acceleration and the PI- controlled load reference speed. SOLUTION: In a double inertia resonance system 110, two moments of inertia are connected to a shaft that has both flexibility and rigidity. A state observer 120 detects the torque (u) and position of a motor and estimates the speed (WL) and disturbance (TL) of the load. A load acceleration estimator 130 estimates the load acceleration based on the disturbance (TL) estimated via the observer 120 and the estimated twist torque (TT). A PI controller 140 performs the PI control based on the difference between the load reference speed (W*) and the estimated load speed (WL). The motor is controlled based on the difference between the estimated load reference speed (WL) and the PI-controlled load reference speed (W*). Thus, the system 110 can be stably controlled without causing vibrations.
