Stringent voltage regulation in a DC‐DC boost converter is a classical engineering problems in theory of power conversion. Voltage Mode Control (VMC) of boost converter is difficult for two principal reasons. First and foremost, of these two reasons, is the converter's non‐minimum phase (NMP) behavior that arises due to the presence of the dynamic right half plane zero (RHPZ) in control to output (c2o) transfer function in VMC. Second reason is the presence of parametric uncertainties* in converter during its continuous conduction mode (CCM) operation. This paper combines theory of smith predictor with boost converter for (i) analytically computing gains of PID controller, (ii) design of a low pass filter to deal with challenges posed by dynamic RHPZ. This two degrees of freedom (2‐DOF) control scheme is analytically derived as a function of the converter's parameters. Gains of PID controller, deduced in terms of circuit's parameter, are used in sequel for extensive simulation analysis of the converter's control loop. Results in this paper establish that the proposed 2‐DOF‐SP outperforms certain well known control schemes used in regulating output voltage and disturbance attenuation in boost converter.
