...Jing Sun; Yan-An Yao This paper presents a new concept of torque balancer for reducing the input torque fluctuation of a mechanism. The proposed active gear balancer consists of a differential gear train and a servomotor. By adjusting the control function of the servomotor, the input torque...

...Pei-Lum Tso This paper focuses on a hybrid-driven servo press, which uses not only a servomotor but also a regular ac motor with a flywheel. A PC-based control system is developed based on both feedback and iterative learning control theories on a prototype. The stamping performance, improved...

Vandenberghe This paper develops a general framework to synthesize optimal polynomial splines for rigid motion systems driven by cams or servomotors. This framework is based on numerical optimization, and has three main...

In a third study, the versatility of the framework is illustrated by generating time...

... suitable non-actuated variables of the chosen legs, need to be placed in addition to the ones normally embedded in the servomotors, i.e., the sensors which measure the actuated variables. From a mathematical point of view, the algorithm is built on the polar decomposition of a matrix and has inherent least...

...A. Basu; S. A. Moosavian; R. Morandini A servo system moves a mass from one position to another as quickly as possible. A servo motor requires very high short term torque and should be able to accelerate and decelerate very quickly. In other words, a servomotor should be able to produce high torque...

..., the hydraulic presses are flexible (their motions can be programmed) and accurate, but are expensive to build and to operate. Recently, there are mechanical presses driven by servomotors. They could perform as flexible as hydraulic presses with high speed. Nevertheless, they are even more expensive to build...
