Full order terminal sliding mode (FOTSM) control is designed for two-port soft open point (SOP) in this paper. The structure of the two-port SOP includes rectifier side and inverter side. The control system on the rectifier side is proposed to stabilize the DC side voltage. A fast full-order terminal sliding mode controller is applied to the current loop to achieve accurate and rapid current tracking performance in the situation of parameter perturbation. And the chattering can be eliminated completely under the designed integral-type control law, so that the continue control signals can be obtained. The control system on the inverter side is proposed to regulate the output power. And the application the FOTSM controller realizes the flexible and accurate power adjustment under a disturbed condition. The SOP provides flexible and accurate power regulation in distribution network. The excellent dynamic performance and anti-disturbance ability of the designed controllers are demonstrated by the simulation results.
