“…Since DC motors of series excitation always operate in the loaded mode, electrodynamic processes in the electric motor should also be modeled taking into account the load. This can be confirmed by studies presented in works by [4][5][6]. The authors show relationship between the nature of load and mechanical characteristics of DCM.…”

The aim of the work is to develop a mathematical model of the traction motor of the pulsating current of an electric locomotive taking into account the magnetic losses in the motor steel to determine the starting parameters depending on the voltage of the armature winding. Methodology. Mathematical modeling of electromagnetic processes in a traction motor of pulsating current is applied taking into account the nonlinear nature of the armature inductance, the inductance of the excitation winding and the nonlinear nature of the universal magnetic characteristic. The magnetic losses in the steel of the traction motor were taken into account by establishing the dependence of these losses on the frequency of reversal, the magnetic flux in the magnetic circuit of the motor and the geometric dimensions of the motor. Results. The mathematical model of calculation of starting parameters of the traction engine of the pulsating current of the traction drive of the electric locomotive of alternating current taking into account the equation of instantaneous value of losses in engine steel is developed. The dynamic characteristics of the traction motor with pulsating current are obtained. It allows to investigate starting parameters of the traction engine on the basis of the received mathematical model and to design elements of the traction drive of the electric locomotive according to the specification, to choose optimum design parameters. Originality. For the first time a comprehensive study of the pulsating current traction motor was carried out taking into account the nonlinear nature of the armature inductance, excitation winding inductance and nonlinear nature of the universal magnetic characteristic and taking into account the magnetic losses in the motor steel. Practical significance. The model of the traction motor of pulsating current taking into account losses in steel of the engine on the basis of the carried-out calculation is developed. Experimental studies have confirmed the adequacy of the model, which allows to apply the obtained model to develop a mathematical model of an AC electric locomotive to study the electrodynamic processes in it at different modes of operation of the electric locomotive.

“…A DC brushless motor is adopted as the loading motor here due to its fast dynamic response, high flux density and power factor. 23 Unlike traditional loading systems, the loading motor of the torque loop in the double-loop loading system moves synchronously with the rudder along with the motion of the position loop. At the same time, its output shaft is connected with the rudder through a torque sensor to apply the desired load torque.…”

In the hardware-in-the-loop simulation, the goal of electric loading is to realize the accurate tracking of the torque signal and test the performance of the aircraft actuator system. For some high dynamic aircraft, it is necessary to reduce the influence of the surplus torque to increase the system frequency band. This paper introduces a new electric loading system which adopts a double-loop servo motor as the torque loading mechanism. It applies two loops to track the position of the rudder and the aerodynamic load spectrum respectively. For the purpose of reducing the disturbance between two loops of the scheme, a two-DOF H∞ robust controller is designed, which improves the robustness of the system effectively. The simulation results show that the new system increases the upper limit of 25 Hz frequency band of the traditional single-loop system with PID control to the maximum of 40 Hz. The double-loop system thereby meets the technical requirements of the hardware-in-the-loop simulation experiment for high dynamic aircrafts.

Public transportation is a major part of developing an advanced and modern city. Progress in public transportation is needed to be planned and realized to deal with the development of the city together with population and economic growth. The use of the Trans Metro Pekanbaru bus transportation is not in line with the development and progress of the City of Pekanbaru, which wants to be a smart city, where the role of the Internet of Things (IoT) needs to be realized in building smart cities and currently the use of the Trans Metro Pekanbaru bus in Pekanbaru is still becoming a problem. it needs to be resolved like the Trans Metro Pekanbaru bus lane which still uses a shared lane which causes congestion and lack of good trafic regulations. Trans Metro Pekanbaru bus transportation is still weak in terms of arrival and departure times. Trans metro Pekanbaru has not yet been integrated in a system that can be monitored centrally through the application of an application system based on the Global Positioning System (GPS). To overcome this problem, it is necessary to have the Trans Metro Pekanbaru bus transportation in the form of a prototype line follower robot which is a solution to overcome this problem. The purpose of this research is to make the line follower robot as a trans-metro silmulation bus for Pekanbaru become a smart city that is able to serve and facilitate the public's need for public transportation towards the industrial revolution 4.0. Line follower robot is a robot that works by following a line in the form of a road such as a traf ic lane, where the robot works using photodiode sensors and ultrasonic sensors as proximity sensors so that it stops automatically at every stop or place where passengers rise and fall. Line follower robots are automatically controlled so programming code and fuzzy algorithms are needed. Line follower robots are also equipped with Closed Circuit Television (CCTV) to determine passenger conditions.
