In modern industry, the accuracy of the linear positioning of various mechanisms can reach 10−6 mm and even more. Screw and belt drives or pneumatic mechanisms with increasing demands for speed, throughput, programming of working cycles revealed the shortcomings of these solutions.
The technology of a direct drive of a linear motor provides a much better approach to solving positioning problems. This technology involves the direct application of electromagnetic force without using a belt, a ball screw drive or other intermediate link. A linear motor performs a direct linear movement, without converting the rotational motion into a translational one. The authors of the article present the calculation and study of a neural regulator for a linear motor control system. Comparison of two control methods has been carried out: with the PID controller and with the neural controller. When comparing, the parameters of the linear motor have been changed. The control system with the neural regulator showed better dynamic characteristics than the system with the PID controller. The influence of the weights-coefficients in the neural regulator has been investigated, the most critical coefficients which significantly affect the dynamics of the system have been determined.
