Title: Position sensorless motor drive device
Inventor: MIYAZAKI SHINICHI
IPC: H02P6/18
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To prevent step-out and stably drive by performing commutation always at the optimum timing, by determining a quantity of delay in an electrical angle required for delaying a commutation pulse up to an optimum commutation point depending upon the peak value in a detected current. SOLUTION: In order to cancel a lead phase deviations generated in rotor position signals X, Y, Z due to a distortion occurring in a terminal voltage integration waveform of a motor 1, a current flowing to a stator winding accompanied with the rotation of a rotor or a current flowing out from the stator winding is detected as a current value equivalent to the detected value. The detected current is converted into digital values by A/D converter 6 and the peak value (peak-to-peak) of a current waveform is retained by a peak hold circuit 7. From the detected current value of the peak of current waveform, the quantity of delay d of electrical angle corresponding to the current waveform is determined from a leading angle adjusting circuit 8, and the quantity of delay d in electrical angle reflecting to the commutation timing is actually determined and output.

IPC: H03L7/06
Filed: 1990-09-05
Abstract: PURPOSE:To attain quick locking to all read data frequencies by devising the circuit such that a loop gain of a PLL circuit is changed attended with a change in a frequency of a read data. CONSTITUTION:A gain switching control section 6 detects a frequency of a current read data and detects a mode by an external mode switching signal and gives a command of gain switching depending on the detected mode and frequency. A gain arithmetic section 3 receives the command to fetch a current phase detection signal and to decide a gain in response to the gain switching command from the control section 6. The phase detection signal and the gain are subject to multiple processing and adds the result of multiplication to the current phase control signal. The result of addition is a control voltage of a VCO 5 via a D/A converter 4. Then a loop gain of a PLL circuit is decided corresponding to the read frequency and quick locking corresponding to all the read frequencies is implemented.

Title: Optimum track planning method for manipulator
Inventor: USUI SHIROU
IPC: G05B19/4155
Filed: 1993-08-17
Abstract: PURPOSE:To provide an optimum track planning method which can applied to a manipulator that is actually used in the present industrial field. CONSTITUTION:The resolving methods are shown to two large problems. First, no optimum solution is acquired in a conventional track planning method since a space path and a time path are alternately planned. In this problem, the optimization term related to the space path/time track and each limit term are expressed in the form of an extended Lagrangian function for an evaluation function. Thus the problem is solved when both the space path and the time track are simultaneously planned. Second, much time is needed for planning a track since the calculation value of the inverse dynamic is increased in a polynomial order in response to the increase of the number of articulations. In this respect, a neural network where the inverse dynamics and the time scheduling are combined together in response to the planning of the space path and the time track is used. So that the calculation value can be suppressed down to a lower order compared with the use of a mathematical model. Thus the time needed for calculation can be extremely shortened.
