Steering Initiations TRIZ Cases
- Hydrofoil Motion Control Using Wave Prediction and AoA Constraints
A neural-network controller predicts wave acceleration ahead of a hydrofoil and adjusts AoA to minimize ride acceleration in irregular seas.
- Vessel Steering Control for Roll Suppression With Low Computing Load
A split steering-angle control scheme suppresses vessel roll while holding azimuth, avoiding heavy memory use and high-speed computation.
- Ship Steering Control with Parallel Thrust Parameter Setting
Parallel input of forward and reverse thrust parameters cuts ship steering setup time while enabling real-time confirmation of propulsor response.
- Dual-Cable Steering Assembly to Eliminate Compression Wear
Two tension-only steering cables and a pulley prevent buckling in marine actuation, reducing hose wear and extending service life.
- Marine Docking Control Interface With Adaptive Buffer Distance
Adaptive buffer distance and velocity limiting help marine vessels avoid collisions while still allowing controlled docking and launch.
- Marine Propulsion Control for Proximity Sensor FOV Expansion
By inducing vessel roll or pitch with existing propulsion devices, proximity sensors capture more obstacles without adding sensors.
- Docking Assist Control Using Perimeter Sensors in Crowded Conditions
Perimeter sensor fusion guides steering and propulsion for accurate docking in crowded conditions and under wind or water-current disturbances.
- Adaptive Autopilot Control for Stable GPS Track Keeping
High-bandwidth turn-rate and GPS feedback stabilizes cross-track control, reducing lag, noise, and oscillation across vehicle types.
- Hull Position Control Using Error Distance and Approaching Speed
Throttle control based on error distance and approaching speed keeps a hull near a fixed point without large-scale positioning systems.
- Watercraft Propulsion Control for Automatic Bow-Stern Target Positioning
Automatic bow or stern mode selection moves a watercraft to a target spot faster and simplifies station keeping control.
- Watercraft Follow Control Using Lead Detection and Autopilot
A detector and digital controller let a host watercraft track a lead craft, hold distance and alignment, and reduce driver workload.
- Unmanned Boat Dynamic Positioning With Non-Singular Finite-Time Control
A prescribed-performance controller combines non-singular finite-time control and fuzzy saturation compensation for precise unmanned boat positioning.
