Passivity-based Control Method in Boost Chopper Type Slip Energy Recovery System

Aiming at boost chopper type slip energy recovery system's indeterminate model and strong nonlinear character, also the disadvantage of the traditional control scheme, passivity-based control scheme is applied to solve these problems. The equivalent circuits is firstly established and then the Euler-Lagrange model. The passivity-based control scheme is deduced by using this Ruler-Lagrange model. Matlab/Simulink is used to simulate the system and good result is shown.
