Diagnostics of Actuators of Machine Tools Drives According to the Identifiability Criterion by the State Space

Abstract: Currently, in view of the fact that almost all the tasks of the practice of controlling CNC machine and robot drives cannot be accurately represented by linear models, and there is no solution to non-linear models in the general case, a very important task is to develop control algorithms based on discrete models. Discrete models of nonlinear systems assume variable state, control, and measurement matrices that determine an infinite number of variants of this model. Therefore, some tool is needed to calculate … Show more

“…The vibration response obtained from analytical model and experiments can be further analyzed by using different techniques available such as statistical and signal processing in the spectrum and its diagnostic performance is tested for comparative fault detection [20]. In [21] analysed methods for vibration diagnosis of electrical systems and gearboxes. In the case of gears, it can be noted that the oscillation of the gears is determined by the meshing frequency and harmonics due to the variable stiffness during meshing [22].…”
