Design of Inverter Voltage Mode Controller by Backstepping Technique for Nonlinear Power System Model

Abstract

Modelling systems are a new sort of electrical network that can be easily adapted. Dispersed generators are linked to a microgrid using voltage source inverters. Nonlinear modelling systems are used in this study to create an inverter voltage mode controller for power systems to control power supply volatility. Controller for a nonlinear inverter that operates in voltage control mode is proposed. The primary goal is to ensure that the output voltage of the system matches a predetermined standard. Once the system model is completed, the controller is constructed using the backstepping method. After the control law is developed, several simulations are run to test the proposed controller's performance. According to simulation findings and formal analysis, the output voltage matches the reference voltage with global asymptotic stability. The accomplishment of this work is that the controller built, works in both grid-connected and inverter voltage modes of microgrid operation.

Robust adaptive backstepping control of H‐bridge inverter based on type‐2 fuzzy optimization of parameters

“…In [39], BSC was initially introduced as a beneficial control technique through the successful rejection of linearly parameterized mismatched and matched uncertainties. Additionally, BMC has been applied to a variety of power inverter topologies in both adaptive and non-adaptive methods to increase the method's efficiency while requiring less complexity [40,41]. These studies demonstrated lower tracking error and transient overshoot with quick responses, but the gains of the controller were tuned using conventional approaches, increasing dependence on error.…”
