  • Adaptive cascade control algorithm
    Patent number: 6240324
    Abstract: A process for performing real-time cascade control for use in controllers. An adaptive process module uses an algorithm to set parameters during system operation to attain the best possible control performance, while providing an easier-to-use system for the user. The algorithm uses a novel adaptive technique to intelligently adjust the minimum and maximum allowable controlled-variable set point limits, under varying load conditions.
