Title: **Sachio Yamanobe: Innovator in Thermal Power Systems**

Introduction

Sachio Yamanobe is a distinguished inventor based in Hitachi, Japan, known for his significant contributions to the field of thermal power systems. With a portfolio of two patents, Yamanobe demonstrates his expertise in control systems that enhance the efficiency and performance of power plants.

Latest Patents

One of Sachio Yamanobe's latest innovations is an **Automatic Control System for Thermal Power Plant**. This sophisticated system features a master controller that manages a turbine in accordance with an externally applied load command signal. The master controller adjusts this load command signal based on the detected pressure of the main steam produced by the boiler, thereby generating a boiler input command signal. This command signal is then communicated to various process controllers including water/steam, fuel, combustion, and draft process controllers, which collectively manage the control signals sent to the respective terminal actuating equipment.

Another significant patent is the **Plant Control Method**, which utilizes the Kalman filter to construct a mathematical model of a power plant. This innovative approach allows for the comparison of a predictive value of a parameter against its actual measurement. When direct measurement of a control object is infeasible, the model is adjusted using easily obtainable parameters, ensuring accurate feedback control. Additionally, any necessary corrections to the system's gain based on the Kalman filter element adjustments further enhance the control system's performance.
