Unconstrained and Constrained Model Predictive Control using Wiener Models: An Application to pH Neutralization

摘要: Abstract pH control is recognized as an industrially important, yet notoriously difficult problem. It proposed, however, that Wiener models, consisting of a linear dynamic element followed in series by static nonlinear element, are ideal for representing this and several other processes. They relatively simple requiring little more effort development than standard step response model, offer superior characterization systems with highly gains. In paper model predictive compared experimentally to both PID MPC, the effects output constraints modeling error also being considered.
