Linear model predictive control (LMPC) is well established as the
industry standard for controlling
constrained multivariable processes. A major limitation of LMPC is that
plant behavior is described
by linear dynamic models. As a result, LMPC is inadequate for highly
nonlinear processes and
moderately nonlinear processes with large operating regimes. This
shortcoming coupled with increasingly
stringent demands on throughput and product quality spurred the
development of nonlinear model predictive
control (NMPC). NMPC is conceptually similar to its linear counterpart
except that nonlinear dynamic
models are used for process prediction and optimization. The purpose of
this WebCAST is to provide an
overview of current NMPC technology with a focus on the real-time
implementation issues required to obtain
a computationally efficient controller. The necessary background will be
introduced by reviewing basic concepts
of nonlinear process modeling and optimization. The principles will be
illustrated with a highly nonlinear
cryogenic air separation column model.
