Claim One:
1. A method of automatically tuning a multivariable model predictive controller (MPC) for a multivariable process that comprises the steps of: (a) identifying a process model for the multivariable process; (b) calculating closed-loop transfer functions for performance and robustness as functions of tuning parameters for the MPC wherein the process model is used to calculate the closed-loop transfer functions or gain functions; (c) identifying at least one performance requirement for the MPC and transforming the at least one performance requirement into constraints on frequency responses of the closed-loop transfer functions or gain functions; (d) identifying at least one robustness requirement for the MPC and transforming the at least one robustness requirement into constraints on frequency responses of the closed-loop transfer functions or gain functions; and (e) determining optimal tuning parameters with respect to performance and robustness.
