Implementation of MAPLE procedures for simulating an industrial multi-stage evaporator

MAPLE procedures have been developed to carry out the analyses and the design of state feedback laws for square nonlinear control affine process systems using differential geometric theory [1, 7]. A procedure has also been developed to carry out the closed-loop simulation of nonlinear processes with MIMO Globally Linearizing Control (MIMOGLC) The procedures are developed in MAPLE 5.4 [17, 18] environment. The procedures are combined as a MAPLE package called nlcontsys. The use of nlcontsys package was demonstrated on a double-effect [11] and a five-effect evaporator [12]. The results showed that the package lcontsys can be readily used for the analysis and design of nonlinear control systems using differential geometric theory [1]. Continuous development of the nlcontsys package is being undertaken.
