The manipulative robot basically consists of three proportional eletropneumatic valves and three pneumatic cylinders, and their parameters are identified in real-time by the Recursive Least Squares (RLS) method. In the possession of the system s model, adaptive of Dahlin Minimum Variance (DMV) are planned and implemented aiming the position control of the manipulative robot s effecter organ. Finally, experimental results are presented, as a way to assess the manipulative robot s performance. / O objetivo do presente trabalho é modelar e controlar em tempo real dois elos de um robô manipulador eletropneumático de três graus de liberdade (3GDL) cartesiano. O robô manipulador é constituído basicamente por três válvulas eletropneumáticas proporcionais e por três cilindros pneumáticos, e seus parâmetros são identificados em tempo real pelo algoritmo dos Mínimos Quadrados Recursivos (MQR). De posse do modelo do sistema, controladores adaptativos de Dahlin-Variância Mínima (DMV) são projetados e implementados visando o controle de posição do órgão efetuador do robô manipulador. Finalizando, são apresentados resultados experimentais, como avaliação do desempenho obtido pelo robô manipulador.

Adaptivní optimální regulátory s principy umělé inteligence v prostředí MATLAB - B&R / Adaptive optimal controllers with principles of artificial intelligence

Mrázek, Michal January 2008 (has links)
Master’s thesis describes adaptive optimal controller design which change parameters of algorithm based on the system information regard for optimal criterion. Generally, the optimal controller solves the problem of minimum states vector. Problems of desired value and steady-state error are solved by variation in optimization algorithm.
