A new control approach for speed tracking and synchronization of multiple motors is developed, by incorporating an adaptive sliding mode control (ASMC) technique into a ring coupling synchronization control structure. This control approach can stabilize speed tracking of each motor and synchronize its motion with other motors' motion so that speed tracking(More)
To satisfy the manufacturing of pistons with complex profile and high accuracy demand, the shaping approach of non-cylinder piston surface with CNC turning is studied in this paper. Piston surface is divided into three characteristics of middle-convex, ellipse, and varying ellipse. And three corresponding processing algorithms are proposed. By using the(More)
