چکیده

Rezumat. În această lucrare est e propusă o arhitectură de control cu structură vari abilă pentru comanda unui robot redundant. Cooperarea actuatorilor robotului, pentru efectuarea unei sarcini robotice, se realizează prin alocarea dinamică de sub-sarcini robot, pentru fiecare sub-controler al arhitecturii. Algoritmul de control al unui sub-controler autonom se bazează pe matricea Jacobian a robotului. Algoritmul de estimare a elementelor matricei Jacobian utilizează matricea de covarianŃă. În lucrare este folosită tehni ca factorizării matricei de covarianŃ ă pentru identi ficarea direcŃiilor redundante din spaŃiul de mişcare al actuatorilor. Abstract. In this paper, a control architecture with variabl e structure for redundant robot is proposed. The cooperation of the robot’s actuators, to realise a robot task is made by the sub-tasks dynamically allocation for each sub-cont roller of the archit ecture. The control algorithm of a sub-cont roller with sel f-governing is based on robot Jacobian matrix. The algorithm for the estimation of Jacobian matrix’s elements uses the covari ance matrix. In this paper, the factorization technique of the covariance matrix for the identi fication of the redundant directions inside the actuator motion space is used.

În această lucrare, considerăm o arteră rutieră urbană şi studiem problema controlului adaptiv al semafoarelor, utilizând informaţii de trafic în timp real. Fluxul de trafic în ariile urbane depinde de comportamentul şoferilor, de modul de control al traficului şi de factorii de mediu. Pe baza acestui context şi datorită creşterii anuale a numărului de vehicule în ariile urbane, autorii s-au or...

Function Approximation Approach for Robust Adaptive Control of Flexible joint Robots

This paper is concerned with the problem of designing a robust adaptive controller for flexible joint robots (FJR). Under the assumption of weak joint elasticity, FJR is firstly modeled and converted into singular perturbation form. The control law consists of a FAT-based adaptive control strategy and a simple correction term. The first term of the controller is used to stability of the slow dy...

Integer-order Versus Fractional-order Adaptive Fuzzy Control of Electrically Driven Robots with Elastic Joints

Real-time robust adaptive fuzzy fractional-order control of electrically driven flexible-joint robots has been addressed in this paper. Two important practical situations have been considered: the fact that robot actuators have limited voltage, and the fact that current signals are contaminated with noise. Through of a novel voltage-based fractional order control for an integer-order dynamical ...

Adaptive Voltage-based Control of Direct-drive Robots Driven by Permanent Magnet Synchronous Motors

Tracking control of the direct-drive robot manipulators in high-speed is a challenging problem. The Coriolis and centrifugal torques become dominant in the high-speed motion control. The dynamical model of the robotic system including the robot manipulator and actuators is highly nonlinear, heavily coupled, uncertain and computationally extensive in non-companion form. In order to overcome thes...
