Abstract
Boost converter has a right-half plane zero (RHPZ) in the “duty cycle control to output voltage” transfer function. Presence of RHPZ deteriorates the performance of the system and causes stability issues. RHPZ should limits the bandwidth of the system while designing PI controller for voltage mode control (VMC) and current mode control (CMC) for boost converter. State feedback control design offers much flexibility in terms of placing poles according to time domain specifications and its implementation is less difficult than VMC or CMC for boost converter. This paper presents modeling, simulation and microcontroller based implementation of the state feedback design with integral control for a boost converter system. The experimental and simulation results verify the system design and specification.
