Abstract :
Presents the results on the modeling and control of a heavy pneumatic machine designed for handling logs. Although pneumatic systems are used in many applications, control of such systems poses difficult problems because of nonlinearity, such as that caused by friction and the well-known nonlinear volume-pressure relationship. The paper shows that a significant improvement in performance results from modified self-tuning generalized predictive control of pneumatic systems
