The motion planning technique described in this paper has been developed to eliminate or reduce the residual vibrations of belt-driven rotary platforms, while maintaining unchanged the motion time and the total angular displacement of the platform. The proposed approach is based on a suitable choice of the motion command given to the servomotor that drives the mechanical device; this command is...

Most existing techniques which employ DWT (discrete wavelet transform) to detect servomechanism fault events are based on the analysis of measured motor current signals. However, the outcomes of these techniques tend to be unreliable when the motor suddenly accelerates or generates a very high output torque. Accordingly, to reduce the occurrence of false alarms, this paper develops a fault dete...

MANY BIOLOGICAL PROCESSES, especially those involving the functioning of the central nervous system, behave as self-regulatory devices or servomechanisms. The pupil reflex to light is an example of such a process. This paper approaches the problem of a quantitative study by applying servoanalytic concepts and techniques (3, 9). A servomechanism is an automatic regulatory device actuated by the ...

The motion planning procedure described in this paper has been developed in order to eliminate or reduce the residual vibrations of electromechanical positioning systems, without augmenting the motion time (usually imposed by production requirements), nor introducing overtime for vibration damping. The proposed technique is based on a suitable choice of the motion law assigned to the servomotor...

This paper presents a new scheme for variable structure (VS) fuzzy PD controller. The rule base of the controller is tuned online. purpose proposed to track accurately preselected position command servomechanism system. Therefore, this study establishes model using black-box modeling approach; simulations were performed based on real-time data collected by LabVIEW and processed MATLAB. input si...
