Title:
APPARATUS AND METHOD FOR pH CONTROL IN WASTEWATER TREATMENT PLANTS AND OTHER SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2012/173802
Kind Code:
A3
Abstract:
A method includes obtaining (4002) a nonlinear model (3124) that represents a pH of a material (3104) in a process to be controlled. The model is generated using an orthonormal bases function and an ordinal spline bases function. The method also includes performing (4004) non-linear model predictive control of the process using the model. The method could also include generating the model using the orthonormal bases function and the ordinal spline bases function. This could include identifying a distribution (3300) of knots and multiple ordinal spline functions, where each ordinal spline function is associated with one of the knots. The ordinal spline bases function can be generated using at least one of the ordinal spline functions.
