Chaotic Heterogeneous Comprehensive Learning Particle Swarm Optimizer Variants for Permanent Magnet Synchronous Motor Models Parameters Estimation Iran. J. Sci. Technol. Trans. Electr. Eng. (IF 0.657) Pub Date : 2019-12-06 Dalia Yousri, Dalia Allam, M. B. Eteiba, Ponnuthurai Nagaratnam Suganthan
Chaotic response in the permanent magnet synchronous motor (PMSM) is an undesirable performance that may affect motor stability. This unexpected behavior occurs due to the disruption in the system parameters and load disturbance. To control this unwanted performance, it’s essential to introduce a robust method to determine the PMSM model parameters efficiently and expeditiously. Two PMSM models depending

Modelling of a UWB Balanced-to-Unbalanced Power Divider Using Coupled Lines Iran. J. Sci. Technol. Trans. Electr. Eng. (IF 0.657) Pub Date : 2019-11-27 Priyansha Bhowmik, Tamasi Moyra
This work presents a UWB balanced-to-unbalanced (BTU) power divider (PD) using coupled lines and an additional shunt TL in the middle. The even-mode and odd-mode ABCD parameters of BTU PD produce the required analytical design equations. Later, the use of stub-loaded coupled lines in the shunt transmission line enhanced the passband response. The structure is further optimised by varying the impedance

Sliding-Mode Tracking Control of a Walking Quadruped Robot with a Push Recovery Algorithm Using a Nonlinear Disturbance Observer as a Virtual Force Sensor Iran. J. Sci. Technol. Trans. Electr. Eng. (IF 0.657) Pub Date : 2019-11-07 Navid Dini, Vahid Johari Majd
This paper offers a new push recovery method to stabilize the quadruped robots walking on even terrains in the presence of external disturbance forces exerted on the body and legs of the robot. To avoid force sensors, a class of nonlinear observers is usually used to estimate all the forces that are applied to the leg joints. However, such estimations involve permanent errors in the case of fast varying
