Abstract :
Dynamic modeling and controller design for three dimensional (3D) output probability density function (PDF) are studied in this paper. The construction of 3D square-root model and the conditions it should meet under the nature constraint are analyzed firstly. Then based on 3D B-spline basis function, the square-root dynamic model of 3D PDF is set up with output and input data of the system through recursive least square (RLS) algorithm, and a tracking performance index is chosen to design controller based on the 3D square-root dynamic model, at last a dynamic system is constructed for simulation study and the results verify the effectiveness of the presented controller.
