“…The grid resistance R s is shown for modeling purposes. To obtain a single averaged switched model of the whole system, two complementary control signals are considered to be in [13], defining the global operation of the system. This idea signifies the difference regarding other works, where the model of the inverter is obtained for each boost converter.…”

“…To control the output current of the DBI, the sliding mode approach is proposed in the present work for the non-linear inner control loop, due to its inherent properties guaranteeing stability and robustness against variation of parameters with high regulation dynamics, as shown in [21,22]. The analysis here developed has its foundation in the state variables behavior of the dual boost inverter under the presence of a sinusoidal reference introduced in [13]. However, this was solved in [13] for a voltage control loop with a linear load, which cannot be directly extended for a current control for grid-connected applications.…”

“…One advantage of this strategy is the reduction of control loops, which leads to a decrease in the number of required sensors. An extended analysis of the equilibrium point for this control strategy is presented in [13], where the DC component of the capacitor voltages is automatically adjusted to the two-fold of the input voltage.…”

“…One external linear control loop that regulates the grid current through a PR controller, and an internal non-linear control loop that is composed of a switching surface to control the difference between the current of the DBI inductors. This is feasible due to the symmetry of the DBI allowing the control of both DC-DC converters as a single system by means of a unique control signal, based on an extension of the theoretical derivation of the SMC presented in [13]. However, in this paper the system model and controller derivation has been modified to control the output current instead of voltage.…”

Sliding Mode Based Control of Dual Boost Inverter for Grid Connection

Single-stage voltage step-up inverters, such as the Dual Boost Inverter (DBI), have a large operating range imposed by the high step-up voltage ratio, which together with the converter of non-linearities, makes them a challenge to control. This is particularly the case for grid-connected applications, where several cascaded and independent control loops are necessary for each converter of the DBI. This paper presents a global current control method based on a combination of a linear proportional resonant controller and a non-linear sliding mode controller that simplifies the controller design and implementation. The proposed control method is validated using a grid-connected laboratory prototype. Experimental results show the correct performance of the controller and compliance with power quality standards.

“…In recent years, various nonlinear control methods have been applied to the voltage-source converter (VSC) such as hysteresis control [12], sliding-mode control [13], backstepping design method [14], one-cycle control [15], and fuzzy control [16]. These methods can achieve stronger robustness and a larger stability range compared with PI control.…”

An Energy-Based Control Strategy for Battery Energy Storage Systems: A Case Study on Microgrid Applications

et al. 2017

Battery energy storage systems (BESSs) with proportional-integral (PI) control methods have been widely studied in microgrids (MGs). However, the performance of PI control methods might be unsatisfactory for BESSs due to the nonlinear characteristics of the system. To overcome this problem, an energy-based (EB) control method is applied to control the converter of a BESS in this study. The EB method is a robust nonlinear control method based on passivity theory with good performance in both transient and steady states. The detailed design process of the EB method in the BESS by adopting an interconnection and damping assignment (IDA) strategy is described. The design process comprises three steps: the construction of the port-controlled Hamiltonian model, the determination of the equilibrium point and the solution of the undetermined matrix. In addition, integral action is combined to eliminate the steady state error generated by the model mismatch. To establish the correctness and validity of the proposed method, we implement several case simulation studies based on a test MG system and compare the control performance of the EB and PI methods carefully. The case simulation results demonstrate that the EB method has better tracking and anti-disturbance performance compared with the classic PI method. Moreover, the proposed EB method shows stronger robustness to the uncertainty of system parameters.

Summary A novel general purpose three‐phase buck‐boost inverter without need of additional filtering units is presented in this study. The proposed inverter topology is built with moderate numbers of elements in terms of the operation advantages and qualities. The buck‐boost converter‐based structure provides obtaining wide‐range output voltage amplitudes lower or higher than the input voltages. A novel hybrid control method that is open‐loop assisted closed‐loop control is proposed for the inverter operation to improve the response performance on various input and output operation conditions. The wye‐connected modular structure of the proposed inverter topology also enables unbalanced three‐phase operation and single‐phase operation for each phase with independent phase voltages and frequencies. An experimental laboratory setup is built for the proposed three‐phase inverter for 0–50 Hz, 0–100 Vp, and 1.5 kW operation values for real‐time application tests. Simulation tests are also applied for the inverter. The obtained results for both the simulation and the experimental tests show that the presented inverter with the proposed hybrid control method is capable of operating in balanced/unbalanced three‐phase and independent single‐phase modes while producing close to sine wave output voltages under 5% THD levels with wide range desired amplitudes and frequencies on different operating points.
