Motion control system of an ultra precision positioning stage with application to IC production is presented. Configuration and master/slave principle of ultra precision positioning stage are pictured. By adopting merits of both coarse and fine stage, a desired motion control system having the capacity of large workspace with high resolution of motion is(More)
This paper proposes a modified teaching-learning-based optimization (TLBO) algorithm for synthesis of thinned square array with low side lobe level (SLL). A local search method based on status switch of elements is imposed to speed up the convergence of the TLBO algorithm and enhance the global searching ability of TLBO. Numerical results of thinned square(More)
In this paper, an annual aerostatic bearing used as a part of air-foot in ultra-precision mechanisms is investigated. The dynamic parameters of aerostatic bearing, such as stiffness, damping and load capacity have been numerically studied based on a fluent model, and the dynamic model of the air-foot stage has also been built. The experiment has been(More)
Compliant force control in space docking is studied. Compliant force control strategy is developed based on the inner loop position control of 6-dof parallel robot in order to simulate push and pull process of forcible alignment in space docking. Considering uncertainties such as parameter perturbations, model perturbations and external disturbances etc.,(More)
