The IMC structure of the system is derived, and its robust stability and zero steady state error characteristics are analyzed. A new control algorithm is developed by adding the variation of the outputs to the index performance. The simulation results show that the method is effective and has zeros steady-state error.展开更多

A docking control algorithm is also described, which a robot employs to approach its current goal. A simple topological navigation algorithm is proposed.

It was formed to bring together three main institutes located in Venezuelan cities and three more institutes located in rural areas, so that to collectively and collaboratively serve the regions in optimal ways. The academic activity started in 1982 graduating engineers and technicians, although less effort has shown by authorities to develop programs in graduate engineering areas. A proposal for designing a structured graduate program is presented. The structured program presented, will hopefully set the basis to develop graduate and doctoral studies in engineering and related areas to the whole university system, and to achieve academic and social development to the country.展开更多
