Title: Control method for robot arm
Inventor: NISHII HISAO
IPC: G05D3/12
Filed: 1990-05-21
Abstract: PURPOSE:To add electric damping to a robot arm and to suppress vibration by negative-feeding back the bounding, angular acceleration and angular velocity of the robot arm, which are obtained by calculating from an operation position and an operation command as against a driving source to the operation command. CONSTITUTION:The robot arm 1 is driven by the operation command given from a control part 6 to the motor 3. A rotary angle detector 7 is mounted on the rotary shaft of the motor 3 and the rotary angle thetam of the motor 3 is given to the control part 6. Consequently, the operating control part 6 gives the operation command to the motor to cancel deviation between a target value U given from an external part and the detection value of the rotary angle thetam by using them. At the same time, the angular velocity of the motor 3 and the rotary angle and the angular velocity of the arm 1 driven in the motor 3 are estimated. Furthermore, electric damping is added to the arm 1 and vibration is suppressed by negative-feeding back the estimated result and thetam to the operation command by using them.

IPC: H04L25/03
Filed: 1990-05-24
Abstract: PURPOSE:To quicken the convergence of a tap coefficient when any nonlinearity is present between codes by applying different updating algorithm to an input signal while using different bit accuracy required for each tap coefficient and adding the result of arithmetic operations so as to obtain a simulating signal with correlation to the input signal. CONSTITUTION:A delay section 1 composed of plural delay elements delays an input signal sequentially at every arithmetic period, and plural tap coefficient arithmetic sections 2 adds the output of a 1st arithmetic series and the output of a 2nd arithmetic series. Then a simulating signal with correlation to an input signal at every delay element is obtained. Moreover, a accumulation section 3 accumulates the simulating signals of the plural tap coefficient arithmetic sections 2 to obtain a simulating signal with correlation to an input signal. Then an adding section 4 subtracts the simulating signal with correlation to the input signal from the signal with the correlation to the input signal to obtain a residual error. Thus, when any nonlinearity is present between codes, the converging time is shortened by providing plural tap coefficients on this filter.
