Abstract
A method and system are disclosed for tuning a Multivariable Proportional-Integral-Derivative (PID) controller in a process plant. The plant can have at least one PID controller for controlling the processes of the plant. The method can include formulating Model Predictive Control (MPC) for the process model of the plant; obtaining a desired (e.g., optimal control) solution for at least one designated (e.g., critical) region in relation to the MPC; determining PID tuning parameters corresponding to the control solution; and tuning the PID controller with the PID tuning parameters.
