Active disturbance rejection control system and control method for first-order pure lag object

摘要: The invention provides an active disturbance rejection control system and a method for first-order pure lag object. comprises signal storage. the have advantages that input variable of controlled object can be acquired by storage, stored in is delayed preset time then outputted to expanded state observer, so output does not correspond previous moment under condition compensated; two variables (the moment) received observer accurately each other, directions unified, accordingly, observation precision improved, closed-loop effect greatly stable performed on
