The synchronous control system is the essential part of the giant forging hydraulic press, its synchronous control performance will directly determine the quality of the product. In order to improve the synchronous control precision, based on the fuzzy system, according to the changing regularity of the eccentric load during the forging process and synchronous control system mathematical model,...

A novel indirect adaptive backstepping control approach based on type-2 fuzzy system is developed for a class of nonlinear systems. This approach adopts type-2 fuzzy system instead of type-1 fuzzy system to approximate the unknown functions. With type-reduction, the type-2 fuzzy system is replaced by the average of two type-1 fuzzy systems. Ultimately, the adaptive laws, by means of backsteppin...
