“…The SMC is applied for the current-loop control of a GSI because of its robustness and overshoot-free fast tracking ability [13], [35]. The development of the current-loop SMC contains three parts: designing sliding-mode surface functions, obtaining voltage control law, and specifying SMC approaching strategy.…”

In this paper, a fully distributed hierarchical control strategy is proposed for operating networked gridsupporting inverters (GSIs) in islanded ac microgrids (MGs). The primary control level implements frequency and voltage control of an ac MG through a cascaded structure, consisting of a droop control loop, a virtual impedance control loop, a mixed H 2 /H ∞-based voltage control loop, and a sliding-mode-control-based current loop. Compared to conventional proportional-plus-integral-based cascaded control, the proposed cascaded control does not require a precise model for the GSI system. The proposed secondary control level implements distributed-consensus-based economic automatic generation control and distributed automatic voltage control, which integrates the conventional secondary control and tertiary control into a single control level by bridging a gap between traditional secondary control and tertiary control. Simulation results demonstrate the effectiveness of the proposed hierarchical control strategy. Index Terms-Automatic voltage control (AVC), distributed consensus, distributed hierarchical control, droop control, economic automatic generation control (EAGC), grid-supporting inverter (GSI).

“…The multilevel inverter topology, which was first introduced in 1975 [5], became popular over the years due to the fact that it was able to provide less disturbances and offered the possibility to function at lower switching frequencies compared to the ordinary three-level H-bridge inverters [6]. Various types of controllers such as hysteresis [7], sliding mode [8] and fuzzy logic [9] have been proposed for multilevel inverters over the years, mainly to maintain output voltage regulation and good dynamic performance. In recent years, there is an emerging interest on the development of a controller based on the concept of passivity that exploits the total energy of the system [10], [11].…”

This paper presents an extension work on the application of interconnection and damping assignment passivity-based controller (IDA-PBC) from the conventional H-bridge inverter to a 5-level Cascaded H-bridge Multilevel Inverter (CHMI). With the controller, the inductor current and the voltage capacitor track the desired reference of the inverter to ensure that the output voltage maintains its regulation while the Total Harmonic Distortion (THD) is kept at low levels with fast transient response. It is designed based on the Port-Control Hamiltonian theory exploiting the dissipation properties of the averaged model of inverter circuits. The results obtained have proven that the IDA-PBC previously developed for the H-bridge inverter can be easily extended and applied to the CHMI circuit. The simulation results showed that the IDA-PBC is able to maintain the output voltage regulation in both circuits in the case of no-load to full-load condition, load uncertainty, and structural uncertainty while maintaining THD of less than 5%. However, in all cases, CHMI has shown better performance in terms of THD percentage and transient response compared to the H-bridge inverter, which are 290 µs and 150 µs respectively.

“…In recent years, many attempts have been made to develop various control schemes for PWM inverters, to meet the above mentioned requirements. Some of the schemes are Fuzzy adaptive proportional-integralderivative (PID) control [3], dead beat control, one sampling ahead preview control, and sliding mode control [4][5].…”
