نویسندگان
چکیده
When the linear active disturbance rejection control (LADRC) is applied for voltage-controlled inverter, discrete period and measurement noise limits observer bandwidth, which affects anti-disturbance performance of system. This results in a poor ability to deal with output voltage fluctuation under load switch. In this paper, novel LADRC strategy based on known compensation proposed inverters. Firstly, original scheme designed. The dynamic robustness system are analyzed by root locus diagram, studied through amplitude-frequency characteristics. Then partial model information current treated as introduced extended state (LESO) improve observation accuracy. difference compared stability LESO analyzed. Finally, effectiveness verified simulation experimental results.

Voltage Control of Three Phase Inverters by Using Active Disturbance Rejection Control
Control of three phase inverters has been an important issue in recent years. This paper proposes active disturbance rejection control (ADRC) scheme for controlling three phase inverters. The main advantage of ADRC that motivated us for using this controller for inverter is that it is model independent. This controller is used in a double loop structure including an inner current loop and oute...
