摘要：
This work investigates the application of the Linear Quadratic Regulator (LQR) technique to a two-module parallel-connected Current-Mode-Controlled (CMC) Pulse-Width-Modulated (PWM) dc-dc boost converter operating in the continuous conduction mode. New feedback controllers are designed for the modular step-up converter under two different control schemes. The dynamic responses are compared with those obtained using the classical control approach. The role of LQR-based control in providing equal-current sharing among the constituent modules is addressed. Cycle-by-cycle simulations are carried out to validate the analysis.
