Ship Maneuvering K and T Parameters

Ship maneuvering refers to the process of altering a vessel's motion state through control inputs such as rudder angle and thrust. The K and T parameters in ship maneuvering represent the velocity and time constants of the vessel's motion response following changes in rudder angle or thrust. These parameters enable the calculation of the mathematical motion model structure for ship maneuvering, facilitating better understanding of vessel motion patterns and control methodologies. In computational implementations, these parameters are typically derived using system identification algorithms that analyze input-output data from sea trials or simulations. The mathematical model often takes the form of transfer functions or state-space representations where K represents the gain coefficient affecting response magnitude, and T represents the time constant governing response speed. Common implementation approaches involve linear regression techniques or Kalman filtering to estimate these parameters from experimental data.
