Abstract :

This project aims to eliminate the voltage steady-state error and attain high-accuracy current estimation without using current sensor. The eradication of voltage steady-state error and achieve high-accuracy current estimation the comprehensive compensation strategy is used. This comprehensive compensation strategy algorithm cannot effectively riddance the output voltage steady-state error, so fuzzy logic controller is implemented. A digital current-mode controller for dcdc converters is introduced. The current control mode includes current observer and Predictive Current Control (PCC) algorithm. This achieves the highest observation accuracy by compensating for all the known parasitic parameter. By adopting the perfect current observer-based predictive current controller, a boost converter is implemented. The current-mode control is sensorless and depend on constants and inner loop states.
