Flying Object Power Control for Battery Overcharge Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The responsiveness of the gas turbine's output power is low relative to the required output power, leading to potential overcharging of the battery when the electric power demand by the motor is rapidly reduced, as the generator's power generation cannot be rapidly adjusted.
Innovation Solution
A flying object control device and method that determines based on the battery's remaining capacity whether to restrict surplus electric power supply, using the surplus power to increase rotor rotational speed and adjust the elevator's steering angle to prevent battery overcharging, thereby consuming excess power and controlling ascent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gas turbine is used to generate electric power for the motor, then continuous power supply is achieved, but the battery may be overcharged when the motor's power demand is rapidly reduced due to the gas turbine's slow responsiveness
Solution Approach 1:
The control device monitors the battery's charge state and the motor's power demand in real-time, and adjusts the gas turbine's power output accordingly. When the battery is fully charged or the motor's power demand decreases, the control device reduces the gas turbine's power generation, preventing battery overcharging while maintaining continuous power supply capability.
Solution Approach 2:
The system dynamically adjusts the gas turbine's operating state based on real-time conditions. The control device modulates the gas turbine's power output to match the actual power demand, transitioning between different operating modes (full power, partial power, idle) to prevent overcharging while ensuring continuous power availability.
2Object-affected harmful factors
If the generator's power generation is rapidly reduced to match the motor's reduced power demand, then battery overcharging is prevented, but the gas turbine's slow responsiveness makes this adjustment difficult
Solution Approach 1:
The control device implements continuous monitoring of battery charge state and motor power demand, creating a closed-loop control system. This feedback mechanism enables gradual adjustment of the gas turbine's power output to match changing demand, preventing battery overcharging despite the gas turbine's inherently slow response characteristics.
Solution Approach 2:
The control device adjusts the gas turbine's operating parameters (fuel supply, air intake, rotor speed) in controlled increments rather than abrupt changes. This gradual parameter adjustment allows the gas turbine to respond to power demand changes more effectively, preventing battery overcharging while accounting for the system's dynamic limitations.

AI summary
A flying object control device includes: a determination unit that determines, based on a remaining capacity of a battery, whether or not to restrict supply of surplus electric power to the battery, the surplus electric power being a surplus of electric power generated by a generator; and a control unit that, when the determination unit determines to restrict the supply of the surplus electric power to the battery, causes the surplus electric power to be consumed by a motor by increasing a rotor rotational speed that is a rotational speed of a rotor, and adjusts a steering angle of an elevator to restrict ascent of a fuselage caused by an increase in the rotor rotational speed.
