Abstract:
1. A fluid pressure actuator control system for controlling a displacement of one predetermined fluid pressure actuator among at least two fluid pressure actuators to which flows of pressurized fluid output from a common fluid pressure source are individually distributed, comprising: an operating device which operates a flow of said pressurized fluid which is distributed to said predetermined fluid pressure actuator; a first detector which detects an operational state of another fluid pressure actuator among said at least two fluid pressure actuators, and outputs a first detection signal; a second detector which detects an operational state of said common fluid pressure source, and outputs a second detection signal; a control device which inputs said first and second detection signals from said first and second detectors and controls said operating device; and a control origin detector which detects that the displacement of said predetermined fluid pressure actuator has arrived at a predetermined control origin, and outputs a third detection signal, wherein said control device, based on said first and second detection signals, calculates a distribution amount of said pressurized fluid to said predetermined fluid pressure actuator, so that said distribution amount becomes a function of the operational state of said another fluid pressure actuator, and controls said operating device based on said distribution amount which has been calculated, and wherein said control device starts to calculate said distribution amount in response to said third detection signal from said control origin detector.
