The article deals with the impact load decrease methods by the example of a rolling stand electric drive of a hot plate mill 5000 OJSC “Magnitogorsk Iron & Steel Works”. The mathematical description of a synchronous motor, which is used to rolling stand, has been provided. A simulation model was developed based on the mathematical description of the synchronous motor. This model is carried out...
In this paper, we propose an off-line tuning method of the vibration suppression controller gains for 2-inertia system using Fictitious Reference Iterative Tuning (FRIT). FRIT is one of data-driven design methods using only one-shot experimental input-output data without model parameters of the controlled object. We use the modified-IPD speed controller which consists of the 2-degree of freedom PID...
Recently, real-world haptics has been researched for tele-operation system. Conventional bilateral control can achieved corresponding master and slave position and action-reaction law. However, if system has flexible mechanism, performance of conventional bilateral control is degraded. Firstly, vibration occurs at slave load side by its flexibility. Secondly, an error between motor position and position...
This paper deals with a control technique of eliminating the transient vibration generated in a dies-driving spindle of a form rolling machine. This technique is based on a model-based control with a rotational speed sensor in order to establish the damping effect at the driven machine part. A rotational speed sensor is installed in a driven gear, namely a bull gear. A control model is composed of...
