In this work, an internal model controller (IMC) with two-degree-of-freedom has been implemented as a voltage mode controller for the output voltage regulation of a boost-type dc–dc converter that exhibits nonminimum phase behavior due to occurrence of a right-half plane (RHP) zero. The IMC structure provides an alternate parameterization of the conventional feedback controller and is comparatively...
In this work, output voltage tracking problem of non-minimum phase (NMP) boost type dc-dc converter in continuous conduction mode (CCM) is studied under the internal model control (IMC) framework. If it is desired to implement large set-point changes, then the manipulated inputs can get saturated during the transients and the closed-loop performance can deteriorate if no provision is made for anti-reset...
This paper investigates the application of two degree-of-freedom (2DOF) internal model controller (IMC) design approach for output voltage regulation of representative boost type dc-dc converter operated in continuous conduction mode (CCM). This system exhibits non-minimum phase behavior due to occurrence of a RHP zero, which poses limitation in the bandwidth available for any control scheme. The...
