| Abstract: | A control algorithm based on the nonlinear control theory and energy balance is proposed for active filters.It applies the PBC(Passivity-Based Control) with nonlinear feedback in DC voltage compensation control to calculate the harmonic current and ensure the stability of system with time-varying nonlinear load.A passivity-based adaptive sliding mode control is developed to accurately track the reference harmonic current during the line parameter change and load change.It analyzes the control system of shunt active filters from the viewpoint of energy,identifies the "workless forces" and designs the control laws with global definition.It is robust,simple in format,and without singular points.Its effectiveness is testified by the experiments based on dSPACE. |
