Abstract: The present invention proposes a macro-micro integrated compound platform with adjustable dynamic characteristics. When a macro platform mover and a micro platform mover are driven at the same time, the whole large-scale high-speed motion can be realized; when a motion deviation occurs, a micro motion platform can be driven separately to realize the high-frequency motion deviation compensation, because the micro motion platform has small inertia and zero friction and achieves precision displacement output through elastic deformation. The macro-micro integrated compound platform can realize high-speed precision motion through compound motion control, is mounted and used in a manner consistent with the traditional platform, and is convenient to be popularized and applied; a stiffness and frequency adjustment mechanism and a variable damper are arranged, so that the micro motion platform can transfer the motion of a macro motion platform and isolate the vibration at any frequency, and realize high-precision displacement compensation; meanwhile, damping of the variable damper is matched with the stiffness and frequency parameters to ensure the high-precision displacement compensation at any frequency and increase the range of working frequency.

Due to composite motion control, one-dimensional high-speed precision motion can be realized, an installation and use manner is consistent with that of the traditional platform, and the one-dimensional platform is convenient to popularize and use.

Abstract: The present invention is a method of assisted mounting and error compensation for absolute grating ruler. It comprises the following: (1) when mounting a CMOS sensor and a grating ruler body, the CMOS sensor reads an upper and a lower sample windows, and due to an angle existing between the grating ruler body and the CMOS sensor, a difference exists between the numbers of the upper and lower sample windows, and by continually adjusting the grating ruler body or the CMOS sensor, the code reading difference is made minimal so that the angle existing between the grating ruler body and the CMOS sensor is zeroed; (2) when mounting the grating ruler body and a mechanic housing, it is moved by a fixed displacement in a motion direction, and a grating encoding reading is recorded and an error compensating amount is obtained which serves as error compensation value in an actual motion to correct a cumulative error introduced by the angle between the grating ruler body and the motion direction. The invention may automatically calculate the deviation angles between the CMOS sensor and the grating ruler body and correct parallelism errors. Meanwhile, it also provides an error compensation in the case that the parallelism errors between the grating ruler body and the reference direction cannot be corrected.
