Summary:A method and system for process control configuration changes are described. In one embodiment, a method for switching from a first control algorithm to a second control algorithm in a continuous process control system is described. The method, in the one embodiment, includes executing the first control algorithm, deter-mining to switch from the first control algo-rithm to the second control algorithm, and executing the second control algorithm. For at least a first execution of the second con-trol algorithm, at least one state variable used in the second control algorithm is ad-justed.
