A rational square-root B-spline model approximation and control of output probability density functions for dynamic stochastic systems

Based on the analysis of the relationship between the actual weight and the pseudo-weight of the rational square-root B-spline based PDF model, this paper presents a new method to the modeling of the rational square-root B-spline based PDF model and the controller design is discussed based on the model. Both the modeling and controller design algorithms are applied to the simulation study of the molecular weight distribution (MWD) process, the results verify the validity of the algorithms.
