Abstract :
The differential geometry method is proposed to solve the high-accuracy speed control problem of forging machine. Considering the pipe´s effect the model is built as a 6-degree affine nonlinear equation which is equivalent to a linear model through differential geometric feedback linearization. For this equivalent linear model the good performance of speed is gained through a pole assignment method. The simulation shows this method is effective.
