“…However, the performance of a DC motor depends not only on the load torque and the structure of the control law; also, of the parametric changes that occur with the operating time. A determining factor is temperature, both due to the Joule effect and the dynamic friction in bearings [21][22][23][24][25][26]. To this end, adaptive control techniques are considered to regulate the output, despite the parametric uncertainty [27]; nevertheless, the precision of the control depends on the mathematical model, partially de ned in its structure [28].…”

This research proposes to obtain a mathematical model that describes the dynamic operation of a brushed DC motor, to obtain a state function considering the electrical, mechanical, and thermal effects of the DC motor. The dynamic evolution of the proposed function is evaluated by simulation using Matlab software, and by applying different values of the step type inputs for the brushed motor excitation employing pulse width modulation (PWM) to obtain a wide range of operations. Experimental results show that the developed state function, provides a reliable approximation to estimate the voltage, armature current, mechanical torque, and temperature of the brushed DC motor, showing an error percentage of 0.2%.

“…Research interest in studying rotating electric machinery from the combined viewpoints of thermal and electrical processes dates back to the 1950s [40,41]. The model used in the present paper was proposed by [25], and the thermal model is derived by considering the power dissipation and heat transfer [25].…”

In this paper, a sensorless speed and armature resistance and temperature estimator for Brushed (B) DC machines is proposed, based on a Cascade-Forward Neural Network (CFNN) andQuasi-Newton BFGS backpropagation (BP). Since we wish to avoid the use of a thermal sensor, a thermal model is needed to estimate the temperature of the BDC machine. Previous studies propose either non-intelligent estimators which depend on the model, such as the Extended Kalman Filter (EKF) and Luenberger's observer, or estimators which do not estimate the speed, temperature and resistance simultaneously. The proposed method has been verified both by simulation and by comparison with the measurements and simulation results available in the literature.
