Abstract:
1. A parallel drive system comprising: a first actuator and a second actuator that include linearly-moving movable units that are arranged in parallel to each other, respectively; and an arm member that forms a bridge between the movable unit of the first actuator and the movable unit of the second actuator, wherein the parallel drive system further comprises: a position detection unit that detects position information on the movable unit of the first actuator; an acceleration detection unit that detects acceleration information on the movable unit of the second actuator; a first control unit that controls the first actuator based on the position information; and a second control unit that controls the second actuator based on the position information and the acceleration information, wherein the second control unit includes: a first speed conversion unit that converts the position information into first speed information, a second speed conversion unit that converts the acceleration information into second speed information, and a speed synthesizer that synthesizes the first speed information and the second speed information into a synthesized speed.
