摘要:
In a control device for a hydraulic actuator, one end of an oil passage that is provided through a connecting rod, a crankshaft and a crankcase supporting the crankshaft is connected to a hydraulic chamber of a hydraulic actuator provided in a piston connected to the crankshaft via the connecting rod with the other end of the oil passage being connected to an oil reservoir and a hydraulic pressure source via a main switching valve. An auxiliary switching valve is provided in the connecting rod. The auxiliary switching valve causes a downstream side of the oil passage that leads to the hydraulic chamber to open into the crankcase when the main switching valve allows the oil passage to communicate with the oil reservoir.

In a motor control device according to the invention, upon velocity control of a motor, a superimposed signal generating unit 9 outputs a superimposed signal idh of a repetitive waveform, such as a triangular wave or a sine wave. A d-axis current command generating unit 10 adds the superimposed signal idh generated by the superimposed signal generating unit 9d to a d-axis current command idc*0 and outputs a d-axis current command idc*. An axial misalignment detecting unit 11 (11a, 11b, 11c, and 11d) receives the d-axis current command idc* and a q-axis current command iqc* and outputs an axial misalignment angle estimation value Δθ̂. An axial misalignment correction unit 12 receives the axial misalignment angle estimation value Δθ̂ and an actual detected position θm and outputs a position after correction θm′. Therefore, detection and correction can be performed in real time through calculation at a given timing during a normal operation.

In a servo controller according to the invention, a position feedback correction unit (3) calculates a first-axis position feedback signal (pmfb1) based on a first-axis position (pm1) as a self-axis position, and a second-axis position (pm2) as an other-axis position; and a deviation between a model position (pal) and the first-axis position feedback signal (pmfb1) is inputted from a subtracter (5) to a position control unit (4), which performs positional control to output a velocity command. A velocity feedback correction unit (6) calculates a first-axis velocity feedback signal (wmfb1) from a first-axis velocity (wm1) as the self-axis velocity, and a second-axis velocity (wm2) as the other-axis velocity; and the velocity control unit (8) adds a model velocity (wa1) and the velocity command outputted from the position control unit (5), and subtracts the first-axis velocity feedback signal (wmfb1) therefrom, and outputs a feedback torque command (Tfb1) based on the corrected velocity command.
