Latest Patents

Yu-Chang Cheng holds a patent titled "Method and apparatus for PID controller with adjustable deadtime compensation." This invention introduces a Smith predictor enhanced PID controller, known as SP-PID. The SP-PID controller is designed to transition from a traditional PID controller to a Smith predictor as a tuning parameter changes from 0 to 1. The properties of the SP-PID are thoroughly explored, and a design procedure is provided to ensure robustness. Simulation results demonstrate that the SP-PID effectively utilizes the Smith predictor when small modeling errors occur, while also reverting to a user-friendly PID controller when model quality diminishes. This innovation can be implemented in existing process control computers without incurring additional hardware costs.
