摘要： PURPOSE:To attain the highly accurate speed/position control of a hydraulic actuator by detecting the shift speed and the acceleration to estimate the overrun amount of the stop control and changing one side of the positioning target value, etc. in response to the estimated overrun amount to perform the compensation of data. CONSTITUTION:A proportion control valve 20 is controlled via an amplifier 19 by a speed command given from a control unit 14. Then a hydraulic actuator 1 is driven. The set values of the position, the speed and the stop position respectively are supplied to the unit 14 from a sequence control circuit 21 via each setting units 18, 17 and 13. At the same time, the pressure 3 and the position 2 applied to the actuator 1 are also detected and supplied in the same way via a compensation arithmetic circuit 12, etc. Here an overrun estimating means 7 including an overrun amount arithmetic circuit 11, etc. Then an estimated overrun amount OVR is decided by the detected speed data Dv, the acceleration data Dx and the load condition detecting data Dp. Based on the amount OVR, the data Dx is equal to the value Dxo which is compensated with increase and decrease through the circuit 12. Then the value Dxo is compared 15 with the target value data Sx.

摘要： PURPOSE:To achieve an acceleration detection with a high response without time delay by performing a simple computation using a speed data memorized in succession. CONSTITUTION:A speed detector 10 outputs a speed data Dv indicating the current speed to be inspected in response to a rotary motion or a linear motion to be detected. A shift register 11 is shift contolled by a sampling pulse S so that the current speed data from the speed detector 10 is sampled at the first stage while the speed data of stages is shifted gradually. The output data Dv of the speed detector 10 is applied to a B input of a subtractor 12 while an output DVN at the Nth stage of the shift register 11 is applied to the A input to perform a subtraction of DVN-DV with an arithmetic unit 12. The output DELTADV of the arithmetic unit 12 corresponds to the acceleration per unit time to be inspected corresponding to the N cycle of the sampling pulse S.

CONSTITUTION:The position data DX calculated by a position detector 10 is successively sampled according to the elaspse of time and successively stored in a shift register 11. The output data DX of the position detector 10 is applied to the B-input of a subtracter 12 while a N-th step of the data DXN of the shift register 11 is applied to the A-input of an operator 12. The operator 12 performs subtraction shown by the formula A-B(DXN-DX, (or B-A) to calculate the difference of the position data DX of present sampling timing and the position data DXN sampled before N-times. The difference DELTADX of the position data outputted from the operator 12 shows the displacement amount of an object to be detected per a unit time corresponding to the N-cycle of a sampling pulse and corresponds to the speed of the object to be detected.
