The present invention provides a fuel delivery management system comprising a control module installed on a vehicle to receive delivery manifest data and manage unloading operations The system includes one or more fuel storage modules equipped with valve modules to regulate fuel flow, and one or more sensor modules positioned at a predetermined fuel unloading location. The system further includes an override module for manual valve control during emergencies and a communication module enabling data exchange among the control module, fuel storage modules, sensor modules, and a monitoring module. Each sensor module has a unique identification number and fuel type, continuously tracks the vehicle's position relative to unloading sections, and monitors the position and angular displacement of one or more lids at the unloading sections. The sensor modules detect lid orientation beyond a predefined angular limit and communicate a fault detection alert to the control module, while indicator modules display valve status through color-coded indicators.

[Object] To provide a control input generating device that generates a control input for controlling a pneumatic actuator with high accuracy. [Solution] A control input generating device configured to generate a control input for controlling a pneumatic actuator includes a first control input generation function, a second control input generation function, and an output generation function. The first control input generation function is configured to generate a first control input when an error exists between a target value and a controlled variable. The second control input generation function is configured to, when the controlled variable is varying with time, generate a second control input that increases as the error between the target value and the controlled variable decreases. The output generation function is configured to generate the control input based on the first control input and the second control input. Using the generated control input for controlling the pneumatic actuator can improve the actuator's responsiveness near the target value and reduce overshoot relative to the target value, thereby enhancing the accuracy of operating the pneumatic actuator to reach the target value. This can even prevent overshoot relative to the target value.
