Naslov: Innovative approach for the determination of a DC motor’s and drive’s parameters using evolutionary methods and different measured current and angular speed responses ID Jesenik, Marko (Avtor)ID Ravber, Miha (Avtor)ID Trbušić, Mislav (Avtor) mathematics-12-00042-v2_(1).pdf (5,41 MB)MD5: 39AC6C28D7786230E37E5E6098761413 Angleški jezik Neznano 1.01 - Izvirni znanstveni članek FERI - Fakulteta za elektrotehniko, računalništvo in informatiko The determination is presented of seven parameters of a DC motor’s drive. The determination was based on a comparison between the measured and simulated current and speed responses. For the parameters’ determination, different evolutionary methods were used and compared to each other. The mathematical model presenting the DC drives model was written using two coupled differential equations, which were solved using the Runge–Kutta first-, second-, third- and fourth-order methods. The approach allows determining the parameters of controlled drives in such a way that the controller is taken into account with the measured voltage. Between the tested evolutionary methods, which were Differential Evolution with three strategies, Teaching-Learning Based Optimization and Artificial Bee Colony, the Differential Evolution (DE/rand/1/exp) can be suggested as the most appropriate for the presented problem. Measurements with different sampling times were used, and it was found out that at least some measuring points should be at the speed-up interval. Different lengths of the measured signal were tested, and it is sufficient to use a signal consisting of the drive’s acceleration and a short part of the stationary operation. The analysis showed that the procedure has good repeatability. The biggest deviation of calculated parameters considering 10 repeated measurements was 6% in case of the La calculation. The deviations of all the other parameters’ calculations were less than 2%. differential evolution, artificial bee colony, teaching-learning based optimization, DC motors, electric drive 21.11.2023 21.12.2023 22.12.2023 2024 25 str.
