Abstract

The invention discloses a predictive compensation fractional order PI control method aiming at a fractional order time lag system; the method comprises the following steps: building a fractional ordertime lag system with predictive compensation, wherein fractional order time lag system is a controlled object; building a closed loop control system with a predictive compensation fractional order PIcontroller according to the controlled object; providing a steady state error burst, and determining a reasonable proportion coefficient of the predictive compensation fractional order PI controlleraccording to the steady state error burst, wherein the reasonable proportion coefficient enables the fractional order time lag system to reach the provided steady state error burst in a given time interval or at the fastest speed. An existing fractional order system is poor in a control effect, complex in a design process, and cannot be well applied to the fractional order systems; the predictivecompensation fractional order PI control method can solve said problems.

Description

technical field [0001] The invention relates to the field of control, in particular to a fractional-order PI control method for predictive compensation for fractional-order time-delay systems. Background technique [0002] At present, in fractional order systems, there is a time-delay phenomenon, and the system time-delay will have an adverse effect on the control system. The control effect of the fractional order system is not good, and the design process is complicated, so it cannot be well applied to the fractional order system. Contents of the invention [0003] In view of this, the present invention provides a fractional-order PI control method for predictive compensation for fractional-order time-delay systems to solve the problem that the control effect of the fractional-order system is not good, the design process is complicated, and it cannot be better applied to the fractional-order system. question. [0004] The present invention provides a fractional-order PI...
