“…3. The voltage graphs of the SEPIC converter capacitor shows a decrease in its amplitude in the closed interval, [4,6] sec, while the voltage response in the capacitor C 1 shows an increase its amplitude slightly, which are produced by a regenerative braking of the motor. The graphic in the lower right shows the responses of the inductor currents.…”

“…Nonlinear average models replacing the discrete nature of the switching control in the transistor are commonly used in the feedback control design for DC motor/dc-to-dc power converters. Following the design of these models, speed sensorless controllers were designed [6], [10], [11]. Switched implementations of average dynamic output feedback control laws; by means of a PWM-modulator, are widely known in classic communications and analog signal encoding literature; for novel applications see [8], [9].…”

This article deals with the sensor-less control of a DC Motor via a SEPIC Converter-Full Bridge combination powered through solar panels. We simultaneously regulate, both, the output voltage of the SEPIC-converter to a value larger than the solar panel output voltage, and the shaft angular velocity, in any of the turning senses, so that it tracks a pre-specified constant reference. The main result of our proposed control scheme is an efficient linear controller obtained via Lyapunov. This controller is based on measurements of the converter currents and voltages, and the DC motor armature current. The control law is derived using an exact stabilization error dynamics model, from which a static linear passive feedback control law is derived. All values of the constant references are parameterized in terms of the equilibrium point of the multivariable system: the SEPIC converter desired output voltage, the solar panel output voltage at its Maximun Power Point (MPP), and the DC motor desired constant angular velocity. The switched control realization of the designed average continuous feedback control law is accomplished by means of a, discrete-valued, Pulse Width Modulation (PWM). Experimental results are presented demonstrating the viability of our proposal.

This paper presents a hierarchical control system designed for permanent DC motor powered by a DC/DC Buck converter. Hierarchical controller based on differential flatness property of the plant system is meant to control the angular speed for tracking trajectories applications. This controller provides the voltage profiles that have to be tracked by the Buck converter and consequently a low hierarchy controller is designed to ensure the aforementioned. The low hierarchy controller goal is accomplished by using another control law based on differential flatness that controls the Buck converter. The contribution is validated through numerical simulations.

“…The fact that the current source is non-ideal, leads to a non-passive relationship between the desired motor current and motor velocity [10]. There are ways to address this problem using passive control techniques by controlling the motors velocity indirectly with a switched voltage source and a minimum phase current feedback technique [11], and more recently incorporating the motors back voltage measurement which provides an exact tracking error dynamics passive output feedback controller [12].…”

This paper provides a framework to synthesize l m 2 -stable and L m 2 -stable control networks in which m strictlyoutput passive controllers can control n − m strictly-output passive plants. The communication between the plants and controllers can tolerate time varying delay and data dropouts. In particular, we introduce a power junction which allows even a single controller (typically designed to control a single plant) to accurately control the position of multiple plants even if the dynamics of the plants are different. An illustrative simulated example shows the position tracking performance of the system. We conclude the discussion with two questions for future research.
