Aiming at the voltage tracking problem of the LC inverter, a new prescribed performance controller is proposed. In order to make the voltage tracking error converge entirely according to the trajectory described by the performance function, a new state variable is introduced referring to the integral sliding surface. The specific form of the voltage controller is obtained according to the voltage equation in the dq coordinate frame and the system stability requirement. The adopted control law is easy to implement. It does not need to adjust the parameters repeatedly so that the inverter’s steady-state and dynamic performance indicators can be close to the prescribed values. The MATLAB/Simulink platform simulation experiment verifies the feasibility and effectiveness of the proposed new prescribed performance control strategy.
