In this paper, an exoskeleton robot used for lower extremity walking- assisted is designed. A kind of SAC force servo hybrid control strategy is proposed. In this strategy, the walking-assisted exoskeleton robot can move followed by the human body in a low velocity and other time can provide an output torque for the human body. This function is realized by judging the rotate velocity of hip joint and then switching the control strategy between SAC control strategy and auxiliary force servo control strategy. This kind of SAC force servo hybrid control strategy is verified effective and feasible by walking-assisted test.

This paper describes a model of an autonomous public solar street lighting system powered by photovoltaic panels with energy storage battery and the lighting emission diodes consumer. The MATLAB simulating model was built for the system parameters study (voltages, currents and battery state of charge) under alternating solar intensity, photovoltaic converter efficiency and the system lighting load power. The study was focused on testing of the model under different load power conditions at the same solar power and battery charge capacity. The presented model is also used for studying the charge/discharge processes of different battery types for power plants containing solar and wind renewable sources.
