“…The speed and acceleration of the motor are typically optimized to achieve fast and accurate movement. The PTP control is typically used in applications where the driven mechanism needs to move from one specific point to another with high accuracy and repeatability, such as in pick-and-place operations [2], assembly lines [3], hydraulic presses [4] or medical devices [5]. In CP control, the system moves continuously along a path, such as a curve or a contour.…”

Position control algorithms can be classified into two groups: point-to-point control and continuous path control. For point-to-point control implemented in programmable logic controllers, the speed setpoint is mostly the only setpoint transmitted to the industrial converter. Incorrect settings of the position controller in PLC may lead to position overshoot or oscillations, which are unacceptable in position control applications. The speed control structure in the industrial converter usually has a fixed structure which does not allow the implementation of advanced speed controller. Moreover, standard library blocks for position control encounter difficulties in diagnostics and tuning. To address these limitations, this paper proposes a novel solution for position control that achieves time-optimal speed trajectory during acceleration and enhanced capabilities during deceleration. The proposed controller was verified by simulations of positioning of zinc ingot feeder unit drive and compared with a standard P-controller. Experimental results confirmed the performance of the proposed controller with the industrial application of a feeder unit.

“…Artificial neural networks may need many samples and exhaustive training before good control performance is achieved (TANG et al, 2016). There are no systematic approaches to design fuzzy controllers, it is time consuming and based on trial and error (CSIKÓS; SZ; SÁROSI, 2017).…”

“…This characteristic makes them suitable to power devices in intense electromagnetic field environments without affecting or being affected by these fields, unlike any other conventional actuator. It is still not widely used in industry or outside academia because it is highly nonlinear and difficult to model and control accurately (THANH; AHN, 2006;JOHNSON;PHILIPS, 1999;CHAN et al, 2003;ANH, 2010;MEDRANO-CERDA;BOWLER;CALDWELL, 1995;WU et al, 2009a;SITUM;HERCEG, 2008;TANG et al, 2016;GUO et al, 2021).…”
