摘要
以移相全桥变换器为控制对象,根据相关的电路对移相全桥变换器进行建模,先应用解析的方法设计模拟的PI控制器,并求出相应的参数,然后将其离散化,得到离散域中的数字PI控制器。随后对模拟域和数字域中的PI控制分别进行了仿真测试,并与原系统进行了比较。其分析和结果表明了该设计方法的可行性和有效性。
By phase-shifted full-bridge converter as the control object, model phase-shifted full-bridge converter and with analytical method design analog PI controller to find the appropriate parameters, then discretization is made in discrete domain to got the digital parameters PI controller. Simulation of PI control in analog and digital domains were conducted respectively, and compared with the original system. The analysis and results show the feasibility and effectiveness of the design method.
