Control System Purpose TRIZ Cases
- Liquid Pump Operating State Detection Using Reservoir Pressure
Reservoir pressure sensing distinguishes pumping and inflow strokes in a liquid pump, enabling earlier fault detection and maintenance.
- Liquid Pump Reservoir Pressure Sensing for Stroke State Detection
Pressure sensing in the reservoir distinguishes pumping and inflow strokes, enabling earlier abnormality detection in liquid pumps.
- Wind Turbine Blade Pitch Control for Tower Oscillation Damping
Individual blade pitch uses tower-rotor difference frequencies to damp tower oscillation while reducing pitch wear and energy use.
- Wind Turbine Pitch Signal Shaping for Tower Oscillation Damping
Shaped individual blade pitch signals damp wind turbine tower oscillation while reducing sum-frequency pitching, energy use, and bearing wear.
