Embodiment Construction

[0054] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0055]It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0056] In addition, if there are descriptions involving "first", "second" and s...

Abstract

The invention discloses a cricket control method and system based on a time automaton and relates to the cricket control technology field. The method comprises the following steps of using a Lagrangedynamical equation method to construct a mathematical model of a continuous process of a cricket physical system; using a time automaton modal model to construct mathematical modeling for a continuous, discrete process and control logic of reflecting the cricket physical system and a cricket embedded control system, and an operational rule so as to obtain a hybrid system model of a cricket controlsystem based on the time automaton; collecting small ball position feedback data, wherein small ball displacement difference is a small ball speed; and according to the previously-constructed hybridsystem model of the cricket control system based on the time automaton, acquiring a control quantity so as to control steering engine motion so as to change a motion state of a small ball and realizepositioning of the small ball on a flat plate and track tracking. The hybrid system model can be used to accurately describe a modeling object, can carry out simultaneous modeling on the physical system and the information system and apply to analysis and control.

Description

technical field [0001] The invention relates to the technical field of cricket control, in particular to a time automata-based cricket control method and system. Background technique [0002] The cricket system is essentially a nonlinear complex open-loop unstable system, so it can provide solutions to nonlinear problems in actual engineering and improve the reliability of the actual system. Due to the intuitiveness of control algorithm verification and the simplicity of model understanding, it is often used to test control algorithms. Many scholars have done a lot of research on how to achieve efficient control of the cricket system. The main research ideas are as follows: firstly, the mathematical model of the cricket system is established using the Euler-Lagrangian dynamic equation based on energy conservation. Then the system model is simplified to obtain the general dynamics model of the cricket system, a simplified model ignoring all friction forces, and an input-outp...
