Latest Patents

Douglas M Carr holds a patent for a "Self-tuning controller." This invention provides a method and apparatus for self-tuning a Proportional Integral-Derivative (PID) controller. The controller is designed to manage at least one load characteristic to a predetermined setpoint by calculating values of Proportional Band (PB), Integral Time Constant (ITC), and Derivative Time Constant (DTC). The process involves applying power to the load, establishing a cut-off point to remove power, and determining the slope of a measured value of the load characteristic. The invention also includes storing the calculated values in non-volatile storage for effective load control.
