abstract
Based on a developed neural network one-step-ahead prediction model with two inputs and two outputs, an internal model control (IMC) loop is established for process control of a continuous, snack food frying process. In this multivariable control loop, each control action is computed iteratively by a modified Newton's and gradient descent methods to inverse the process prediction model equation at each time instant. Using this control loop, the time-lags between the process inputs and outputs are compensated. Results of controller simulation of the continuous, snack food frying process are presented.
