Abstract: To solve the strong input and output coupling characteristics problem of
   the nonlinear parts in the field of industrial process control,the
   method was proposed in which a nonlinear model was converted into the
   global linear model using the mathematical transformation in every
   sampling time.Based on above, the output error changes were introduced
   into the objective function and some constraints were added in the
   performance index,and the positions of the actual controlled variables
   were ensured by comparing the actual controlled variables with the
   designed controlled variables,thus the controller can take the
   corresponding actions to realize the iterative predictive control with
   horizon control and multivariable constraints.Simulation results show
   that the algorithm is effective and feasible.
