Control of Alternate Motion Machine with High Inertia Forces
نویسندگان
چکیده
This paper describes the implementation and the validation of a digital controller driving a fourbar mechanism with high alternate motion masses. The control uses a mixed explorative and predictive technique based on off-line model of weight, inertia and friction. Particular care has been devoted to adjust an hybrid (analogdigital) system for the feedback signal acquiring. The control proved to satisfactorly be used to obtain electrical cams up to 250 rpm average speed with sharp acceleration diagrams. The responsiveness of the control permitted to appreciate advantages of motion law harmonic content reduction.

Vibration Analysis of Rotary Compressors
By theoretically analyzing dynamic behavior of the crankshaft, the rolling piston and the blade inrolling-piston rotary compressors, constraint forces and sliding speed at each pair of movable machine elements were obtained, and unbalanced inertia forces and compressor vibrations were evaluated. It was concluded that theoretical results have a goodagreement with experimental ones. Moreover, it ...

This paper deals with the problem of the instability regions of a free-free uniform Bernoulli beam consisting of two concentrated masses at the two free ends under the follower and transversal forces as a model for a space structure. The follower force is the model for the propulsion force and the transversal force is the controller force. The main aim of this study is to analyze the effects of...

The effect of prismatic joint inertia on dynamics of planar kinematic chains with friction is investigated. The influence of the prismatic joint inertia on the position of the application point of the joint reaction forces and on the dynamic response of a planar robot arm with feedback control is analyzed. Larger values of the initial condition response characteristics are observed for larger v...
متن کاملGeneral High Performance Adaptive Robust Motion Control of Machine Tools
Adaptive Robust Control (ARC) is a synergistic combination of adaptive control and deterministic robust control (DRC). It provides a robust performance with predictable transients while avoiding chattering typical in DRC. Antiintegration windup mechanism is built in the ARC and thus the problem of control saturation is alleviated. In this paper, ARC is applied to the motion control of machine t...
