【Abstract】 By analyzing the characteristic of pure-delay control systems and the defect of PID algorithm, the article describes the method about directly designing the digital controller by means of close-loop transfer function when the exact transfer function of known objects is given in the discrete area. Aimed at order I and II systems with pure-delay, it discusses deeply the principle of Dahlin algorithm, and the model, network, network structure, and software programming of digital controllers.更多还原
