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.
- Wind Turbine Blade Pitch Control for Vortex-Induced Vibration
Automatic blade pitch adjustment enters anti-vortex mode within a set window to suppress vibration and limit fatigue loads.
- Wind Turbine Blade Vibration Control via Synthetic Jets
Active flow control devices respond to sensor feedback to suppress blade oscillations without passive power capture losses, extending component lifespan.
- Wind Turbine Tower Oscillation Damping via Converter Control
Converter control modulates generator torque to dampen side-side tower oscillations using measured acceleration data.
- Wind Turbine Power-Limited Control via Speed and Torque Adjustment
A wind turbine control unit manages power output by adjusting rotational speed and torque setpoints.
