Abstract

The invention discloses a two-part consistency quantitative control method suitable for a networked robot system. The control method has the beneficial effects that firstly, the two-part consistency control is popularized to the networked robot system and is mainly applied to practical problems of formation, obstacle avoidance and the like of the networked robot system; secondly, quantitative communication interaction between robots is considered (logarithmic quantization and uniform quantization are considered simultaneously), so that the communication cost between the robots is reduced, anda certain confidentiality effect on information is achieved; finally, input disturbance and uncertain control parameters are set in a robot dynamical model, the disturbance of the control of the networked robot system in an actual scene is simulated, and the control effect is more practical.

Description

technical field [0001] The invention relates to the field of robot intelligent control, and more specifically relates to a bipartite consistency quantitative control method suitable for a networked robot system. Background technique [0002] Consistency control of networked robotic systems has always been the focus of researchers because of its wide application in different fields, such as distributed computing in engineering and computer science, sensor networks, formation control of unmanned vehicles, etc. . Consistency control enables robots to communicate through cooperation to achieve a common state, such as making the car reach the same speed, the aircraft track the same target, and so on. [0003] In a networked robotic system, the dynamics of a manipulator is modeled as an Eulegrangian system with input perturbations and parameter uncertainties. The kinematics and dynamics characteristics of a single manipulator can be expressed by the mathematical model represente...
