In order to ensuring the need of high-accuracy and low cost that the test facility runs scene, this paper suggest that one kind of error drive-based motion curve plans method. Taking developing and testing a test facility as example, planned the motion curve based on error drives, make sure the request designing accuracy for design, carry out rational assignment and combining on accuracy, and give the specially scaling curve to verify the device of track characteristic property. As a result, the method can provide the motion curve planning of the controlling accuracy of the test facility, and the device can operate in stable states and have fine tracking characteristic property always.
