  • Adaptive multivariable MPC controller with LP constraints
    Patent number: 7599751
    Abstract: A method is disclosed for developing and using a high-speed adaptive multivariable controller by removing the dynamics of the PID controllers from a Model Predictive Controller that was developed using identification testing of a process. The resulting multivariable controller, based on final control elements as the manipulated variables is then used in a novel control adaptation with all of the PID controllers switched to manual.

  • On-line dynamic advisor from MPC models
    Patent number: 7444193
    Abstract: A method is disclosed for removing the dynamics of the PID controllers from a Model Predictive Controller that was developed using identification testing of a process. This then allows the creation of a very fast final control element based on-line operator advisor that operates in conjunction with the process so that it has access to real time data and provides an ongoing prediction of the future state of the process as well as the capability to investigate alternate scenarios of control possibilities.

  • Method for removal of PID dynamics from MPC models
    Patent number: 7263473
    Abstract: A method is disclosed for removing the dynamics of the PID controllers from a Model Predictive Controller that was developed using identification testing of a process. This allows creation of valve-based off-line process simulators and provides methods to generate new MPC controllers for complex multivariable process control when a change has been made in any PID control configuration or tuning and to do so without having to conduct new identification testing of the process.
