摘要
通过对Boost变换电路中信号传递函数的系统分析,设计了Matlab/Simulink平台上Boost变换控制的PID仿真模型,分析并实现了其闭环情况下输出电压与电流的精细控制。在此基础上,完成了基于TMS320F2806数字控制芯片的boost升压电路的控制器设计。系统通过128×64字符LCD及4×4键盘实现人机交互功能,并在CCS编译环境下完成了软件开发与调试。性能测试结果表明,输出电压与电流的控制快速灵敏,系统性能稳定可靠。
After the systematic analysis of the transmission function of the signal, a PID simulation module under Boost controlwas designed in Maflab/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.
