Intelligent control of precision linear actuators

This paper presents and compares possible intelligent control designs for p recision motion control applications which are based on the use of linear a ctuators. The control schemes developed include adaptive control, compositi e control using a radial-basis function for nonlinear compensation and an i terative learning control scheme. The mathematical model for a permanent ma gnet linear motor is first presented on which the control designs are based . Theoretical analysis as well as full experimental results are provided fo r the control schemes. Practical issues in the overall implementation of a precision motion control system are also highlighted. (C) 2000 Elsevier Sci ence Ltd. All rights reserved.
