摘要: Abstract Mathematical models of propeller thrust and torque are traditionally based on steady state characteristics obtained in model basin or cavitation tunnel tests. Experimental results showed that these quasi do not accurately describe the transient phenomena a thruster. A recently published dynamic was experimental observations. Describing zero advance speed conditions accurately, this model, however, does work for vessel at nonzero relative water speed. This paper derives large signal includes effects transients flow over wide range operation. The essential accurate control positioning underwater robotics.
