Parallel drive system

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 moveable unit of the second actuator, wherein
• the parallel drive system further comprises:
• a position detection unit that detects position information on the moveable 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, and wherein
• the second control unit is configured to:
• further receive a control signal for controlling a torque of the first actuator from the first control unit;
• have a torque calculation unit that calculates a corrected torque based on the position information and the acceleration information;
• and
• control the second actuator based on an output from the torque calculation unit and the control signal.
