2results about How to "Realize trajectory tracking" patented technology

This invention relates to an event-triggered system regulation and control method in a network control system. This method ensures the safe operation of the network control system even when it is subjected to a DoS attack, achieving actual trajectory tracking and disturbance suppression. Specifically, this invention ensures that the network control system can achieve actual trajectory tracking and disturbance suppression even under DoS attacks; that is, the system's tracking error can be arbitrarily reduced by adjusting the event triggering mechanism parameters. This invention has excellent practicality and accuracy and can be applied to various practical network control systems, such as vehicle networking control systems and networked motor control systems.

The application relates to the field of finished infusion detection, and discloses a quality online detection method and system for finished infusion in a static preparation center, which comprises the following steps: collecting a continuous transmission image sequence, establishing a space affine mapping relationship by using a characteristic anchor point, offsetting a displacement vector deviation through coordinate system alignment, and determining a dynamic displacement trajectory of a target inside a fluid; laterally injecting a linear polarization detection light beam into a detection channel, synchronously collecting scattering light intensity signals by using orthogonally arranged detection channels to calculate a depolarization rate; extracting a background gray value to correct a judgment threshold value, and identifying a solid foreign matter in combination with a motion trajectory and the corrected judgment threshold value; the application captures tiny particles by virtue of anisotropic characteristics of phase interfaces, strips bubbles from deformation interference, realizes self-adaptive matching of detection parameters to optical properties of a liquid medicine, and guarantees high-throughput operation in the field of medical quality control.
