Research on Motion Control of Bio-inspired Fish Swimming Based on CFD-PID Method
摘要
Abstract
Compared with traditional propeller propulsion,underwater bionic propulsion has the advantages of flexibility,high efficiency,and low environmental interference.The movement of fish schools can provide many biological advantages to individual fish.Similarly,individual fish in a bionic school can also gain significant benefits in speed and efficiency.In a tandem arranged bionic school,the rear fish can benefit from the wake field of the front fish by active body oscillation control.Based on the solution of the incompressible Navier-Stokes equations and Newton's second law,a PID control algorithm is embedded to construct a CFD-PID solver that can simulate the self-propelled movement of a bionic fish school through active body oscillation control in a tandem arranged configuration.By dynamically adjusting the oscillation angle indirectly to control the speed through PID,suitable control parameters are sought to achieve the process of the rear fish in the bionic fish school from static to a stable speed.The vorticity field and the speed changes of the bionic fish school is then analyzed.The research results show that,when using PID control method,the appropriate control parameters can enable any bionic fish in the school to reach the converged speed more accurately and quickly.关键词
