“…On the other hand, differential flatness proposals [20] and [21], differential flatness and PI plus sliding modes [22], and linear PI controllers [23], were designed based on a hierarchical approach. Whereas, a GPIO control [24], a nonlinear control [25], a control in successive loops [26], and a robust flatness-based tracking control [27], were developed by considering the differential flatness property. Additionally, a neuronal control [28], neuro-adaptive backstepping controls [29], [30], and an adaptive neurofuzzy H-infinity control [31], were proposed by using the neural networks technique.…”

In this investigation, a tracking control is designed for the angular velocity of the DC/DC Boost converter-DC motor system. To this end, the dynamics of the power supply, generated through a renewable energy power source, is considered in both the mathematical model and the designed control. This latter is proposed by using a two-level hierarchical approach, where the dynamics of the DC/DC Boost converter and the one associated with the DC motor not only are treated as two independent subsystems, but also they exploit their differential flatness property. For the DC/DC Boost converter, an alternative mathematical model of first order is obtained for designing the low-level voltage control. Whereas, the well known second order mathematical model of the DC motor is used for developing the high-level angular velocity control. The robustness and performance of the hierarchical tracking control are verified via realistic numerical simulations and experimental results by using Matlab-Simulink, a prototype of the system, the DS1104 board, and the renewable energy emulator TDK-Lambda G100-17. The results demonstrate and validate the effectiveness of the proposed approach.INDEX TERMS DC/DC Boost converter, DC motor, differential flatness, renewable energy, robust control, solar energy. I. INTRODUCTIONT HE DC motor is an electric machine with several applications [1]. Some of these are at industrial level (pumps, fans, robotics, automation), civilian (home appliances, ventilation, air conditioning), transportation (trains, electric vehicles, aircraft), and renewable energy (motor-generator pair system, solar pumps), among others. Related to industry applications, systems using a DC motor represents, on average, the 60% of electric consumption [2]. Because of this, the renewable energy turns out to be an interesting topic when is focused on feeding a motor. On the other hand, since the power electronics converters has a high efficency when converting electric energy, their application for driving motors feeded by renewable energy power sources is an excellent choice [3], [4]. In this sense, relevant published papers related to the DC/DC power electronics converters connected with DC motors are [5]-[68], being the Buck [5]-[47] and the Boost [48]-[57] topologies the most commonly used.

“…In [5], Ahmad et al designed and compared the performance of PI control, fuzzy PI, and linear quadratic regulator (LQR) algorithms. On the other hand, papers [6][7][8] focused on control strategies based on differential flatness for solving the tracking task. In [9], Bingöl and Paçaci developed software for controlling the DC/DC Buck power converter through neural networks.…”

This paper presents a sliding mode control (SMC) for the “full-bridge Buck inverter–DC motor” system when a photovoltaic (PV) panel is considered as the power supply. The control executes the trajectory tracking task related to the angular velocity of the DC motor shaft without the need for electromechanical sensors. The proposed control is validated through realistic simulation results via Matlab-Simulink. In this regard, the system is constructed by using the electronic components of the specialized power systems library of Simscape. The results of the following four case studies are presented: (i) The performance of the closed-loop system considering two desired angular velocity profiles and three different incident solar irradiance shapes on the PV panel. (ii) An analysis associated with the primary energy source. (iii) A comparison of the proposed SMC versus a passive control. (iv) A study of the current ripple and its relationship with the execution of the tracking control task on the angular velocity.

“…Meanwhile, Sira-Ramírez and Oliver-Salazar in [5] studied the concepts of active disturbance rejection control and differential flatness in two combinations of the Buck converter with DC motors. Moreover, in recent years, several active disturbance rejection control schemes have been developed for governing Buck converter-driven motor systems, e.g., [6][7][8][9][10][11], while the study of controls based on differential flatness enabling solving the trajectory tracking task have been proposed in [12][13][14]. On the other hand, the applications of zero average dynamics of fixed point induction control techniques to control the speed of a permanent magnet DC motor with a Buck converter were detailed by Hoyos et al, in [15][16][17][18].…”

“…This is accomplished if we choose {k 0 , k 1 , k 2 , k 3 , k 4 } as in (5). Since (14) has been ensured to be exponentially stable, we have that ω(t) → ω * (t) exponentially. Now, consider the expressions in ( 8)-( 10), and suppose that ω is constant, i.e., that all velocity time derivatives are zero.…”

By developing a robust control strategy based on the differential flatness concept, this paper presents a solution for the bidirectional trajectory tracking task in the “full-bridge Buck inverter–DC motor” system. The robustness of the proposed control is achieved by taking advantage of the differential flatness property related to the mathematical model of the system. The performance of the control, designed via the flatness concept, is verified in two ways. The first is by implementing experimentally the flatness control and proposing different shapes for the desired angular velocity profiles. For this aim, a built prototype of the “full-bridge Buck inverter–DC motor” system, along with Matlab–Simulink and a DS1104 board from dSPACE are used. The second is via simulation results, i.e., by programming the system in closed-loop with the proposed control algorithm through Matlab–Simulink. The experimental and the simulation results are similar, thus demonstrating the effectiveness of the designed robust control even when abrupt electrical variations are considered in the system.
