“…The speed estimation of the DC engine can be gotten with no speed sensor. As per Chieh-Tsung et al [16], the fundamental commutating of DC engine, the brush, would intermittently slide between the two neighboring commutators.…”

This paper develops an estimator of speeds indirect for a DC motor embedded in an electrical water pump installed in internal combustion engines. The benefit of this technique is that the estimation framework doesn't require a dynamometer or machine-like coupling. The test results were based on the Motor Current Signal Analysis (MCSA) technique that is commonly used in an AC motor and has a great performance for measuring the rotational speed of electric motors. Two tests were used, one with DC motors using a dynamometer to validate the indirect reading of the rotation and another using the indirect estimator of speed developed in this work. This technique had positive results, regardless of the type of current sensor used. The preliminary outcomes from a research center model were introduced to justify the practicality of the proposed estimator of speed.

“…The extraction process was complex and required computing power beyond inexpensive low end microprocessors. Chi and Yin [19] looked at the current ripple in a small 12 V DC motor with three commutator segments and three coils which was used to drive a small pump. The ripple from commutation was much more obvious than that from Hilairet and Auger's 500 W motor and the commutation frequency more easily extracted.…”

This study describes two new methods of sensing the speed of a pulse-width modulation-driven brushed DC motor based on measuring the inductive spikes generated when the motor is turned off. The research has studied the relationship between the rise time or duration of the inductive spike, and the motor current and speed. Computationally inexpensive algorithms have been developed that use either rise time or duration to estimate speed. The algorithms have been implemented on an inexpensive microprocessor and show a speed error of approximately 10% over most of the motor's range of operation. The spike rise time implementation requires an analog-to-digital converter (ADC) as found in many microprocessors, while the spike duration implementation requires only a single digital input thus reducing the cost of the controlling microprocessor. This work has shown that sensorless speed measurement can be based on the inductive spike and has also raised future research questions, such as to the best way to optimise the speed measurement in dynamic situations, and measurement errors to be expected in a mass production environment.

“…Sensorless vector control has been applied to brushless DC motors, induction motors, and synchronous motors [2]- [4]. On the other hand, sensorless control methods of DC motors estimating rotor position or velocity from current ripple have been proposed [5]- [9]. However, these methods cannot estimate rotor velocity continuously since they use current ripple for estimation.…”

This paper proposes position-sensorless disturbance observer (PSDOB) for DC brushed motor (abbreviated as DC motor later). The aim of this method is to suppress disturbance for position-sensorless motion control of DC motor. At first, block diagram of motor system is transformed and disturbance torque is defined as modeling errors between real motor model and nominal model. Next, disturbance torque is estimated from current reference, voltage reference, and measured current. Finally, estimated disturbance torque is fed back to suppress the disturbance torque. Therefore, robust acceleration control can be realized by utilizing PSDOB. The utility of the proposed method is experimentally verified.
