Abstract:Mathematical model of the 3D rigid pendulum constructed by MATLAB, based on experimental platform, fuzzy controller or it combined with the P controller controlled (permanent magnet synchronous motor, PMSM) and posture of 3D rigid pendulum, fuzzy controller programming was edited through LABVIEW, and we could observe control curve of 3D rigid pendulum in PC. The results showed that the fuzzy control strategy was effective for 3D rigid pendulum in actual engineering.
