Mazurov V.M., Fam Van Nguyen Modal controllers for industrial objects with time lag

New structures and calculation procedures for digital modal controllers for second-order plants with time lag are proposed. The key elements of a structure are a second order plant`s digital model, a full-order observer and a non-static state controller. The observer allows to create control object`s coordinates predicted from the time lag value. The proposed controllers ensure significantly higher system`s response speed and demonstrate high stability factor as against conventional PID controllers. They enable high-performance control of inertial, oscillatory, and nonminimum-phase objects with delays in control and measuring channels.
