Converter linear control delay compensation method

The embodiment of the invention provides a linear control delay compensation method for a converter, which is used for solving the technical problems of inherent defects of low control bandwidth and large steady-state error in the existing design method of a traditional controller. By predicting the output of the system at the next moment, the reference value at the current moment is subtracted from the current output value predicted at the previous moment, a new input is generated and sent to the controller, the delay link generated in the application of the traditional control can be counteracted, and the effects of increasing the bandwidth of the system and reducing the steady-state error are achieved. The input of the (k + 1) moment and the output value of the (k + 1) moment predicted at the k moment are subtracted, the difference value serves as the input and is sent to the controller, a closed-loop negative feedback loop is formed, the output value of the (k + 1) moment predicted at the k moment is not
