Design of Control System for Boost Circuit Based on F2806

After the systematic analysis of the transmission function of the signal,a PID simulation module under Boost controlwas designed in Matlab/Simulinkplatform,and the fine control of the output voltage and current of the boostcircuit was realized in closed loop.Then hardware of the system was designed based on TMS320F2806,including Boost circuit andparameter calculation.A 128(64 lattice LCD provided convenient human-machineinterface with 4×4 Key Board.Thesoftware of the system is designed in CCS,and software passed the Matlab/Simulinksimulation test.Final performance shows that the control of the output voltage and current have a higher speed andsensivity,and the Boost Control Systemworks stable and realiable.
