A comparison of the parameters of the transient characteristics of the module-optimized closed-loop transfer current of the positioning system without taking into account and taking into account the deep pulse-width modulation of the supply voltage of the linear motor. Their essential difference on speed, overregulation, static error is established. A method of optimization according to the criterion of current circuit speed is proposed, which allows to realize its transient characteristic

The synthesis of a digital current loop controller is performed, it allows to realize its transient characteristic without over-regulation during a finite number of switching intervals. The results obtained are based on the transfer function of a pulse-width converter, which is a link in the current loop. It is obtained for the case of deep pulse-width modulation based on the statistical linearization of piecewise-linear modulation characteristics of the channels of the pulse-width converter model. The modulation characteristics are obtained as a result of the expansion of the latitude-modular voltage for multiple values of the control coordinate in the Walsh-Fourier series. The number of Walsh functions taken into account depends on the approximation error and the cutoff frequency of the system. References 11, figures 3.
