Abstract
A sensorless control based on the exact tracking error dynamics passive output feedback (ETEDPOF) methodology is proposed for executing the angular velocity trajectory tracking task on the “full-bridge Buck inverter–DC motor” system. When such a methodology is applied to the system, the tracking task is achieved by considering only the current sensing and by using some reference trajectories for the system. The reference trajectories are obtained by exploiting the flatness property associated with the mathematical model of the “full-bridge Buck inverter–DC motor” system. Experimental tests are developed for different desired angular velocity trajectories. With the aim of obtaining the experimental results in closed-loop, a “full-bridge Buck inverter–DC motor” prototype, Matlab-Simulink, and a DS1104 board from dSPACE are employed. The experimental results show the effectiveness of the proposed control.

Summary
Permanent magnet DC motors are used in a wide range of applications [1]. Such applications, for mentioning a few, are: domestic life (kitchen equipment, washing machines, toys, cameras, etc.), public life (autobank machines, automatic vending machines, ticketing machines, etc.), and industry (industrial drives, machine tools, robots, etc.). Inspired by the control applications based on the ETEDPOF methodology, in this paper a sensorless passivitybased control that considers the ETEDPOF strategy and flatness is proposed for the new “full-bridge Buck inverter– DC motor” system. From the aforementioned discussion of the state-of-the-art and motivation of the work, the main contributions of this study can be summarized as follows: 1) To design a sensorless passivity-based control by using the ETEDPOF methodology for solving the angular velocity trajectory tracking task for the new “fullbridge Buck inverter–DC motor” system. 3) To experimentally verify the performance of the control, designed via the ETEDPOF methodology and the flatness concept, for different types of desired angular velocity trajectories For this aim, a built prototype of the “full-bridge Buck inverter–DC motor” system, Matlab-Simulink, and a DS1104 board from dSPACE are used.
