Title: Yasuhiro Tennichi: Innovator in Process Control Technology
Introduction
Yasuhiro Tennichi is a notable inventor based in Hitachi, Japan. He has made significant contributions to the field of process control technology, holding a total of 6 patents. His work focuses on improving the efficiency and reliability of process control systems through innovative methods.
Latest Patents
Tennichi's latest patents include a "Process control method and system with employment of fuzzy inference." This invention involves a process control apparatus that utilizes fuzzy control to reduce rules and membership functions. The apparatus determines a manipulating variable of a controlled object by inputting the present value of a controlled variable and outputting the determined manipulating variable. It features a predicting unit that simulates the controlled object, calculating a control variable after a predetermined time, assuming the present value of the manipulating variable is maintained. This approach simplifies fuzzy inference and enhances noise resistance.
Another significant patent is the "Process control system and method thereof." This system incorporates a timer circuit that establishes operational periods by issuing instructions to start multiple time periods. A periodic operation selection circuit selects control blocks to be computed within each time period based on instructions from the timer circuit. This innovative design ensures that control blocks are executed efficiently, even if computations are not completed within the predetermined time period.
