Saturated system composite nonlinear feedback controller design method based on event triggering

Abstract

The invention belongs to the field of controller design, and provides a new technical scheme for saturated system composite nonlinear feedback control, which realizes the effect of adjusting samplingmoments in real time according to operating conditions of a system, can ensure the stability of the system and can save communication resources. Thus, the technical scheme adopted by the invention isa saturated system composite nonlinear feedback controller design method based on event triggering. The saturated system composite nonlinear feedback controller design method comprises the steps of: firstly, establishing a saturated system model, and designing a corresponding composite nonlinear feedback controller; and designing an appropriate triggering condition based on the composite nonlinearfeedback controller, sampling and transmitting state information of the system only when the triggering condition is met, and adopting a sampling value for calculation by means of the composite nonlinear feedback controller and updating output of an executor, thereby completing a control task of the system. The saturated system composite nonlinear feedback controller design method based on eventtriggering is mainly applied to controller design.

Description

technical field [0001] The invention belongs to the field of controller design, uses an event trigger mechanism to sample the state of a saturated system, and uses the sampling state to design a compound nonlinear feedback controller. Background technique [0002] The tracking problem of the control system mainly solves the tracking of the system output to the reference input signal. Adjustment time and overshoot are two important performance indicators in control problems, but these two performance indicators are mutually restricted, that is, when the adjustment time is short, the response speed of the system is improved, but it will cause a large System overshoot. In practical applications, the commonly used processing method for tracking problems is compound nonlinear feedback control, which is composed of a combination of linear control law and nonlinear control law, and the conversion between these two parts does not include any switching elemental. When the state of...
