A Barrier Lyapunov Function (BLF), which depends explicitly on time, is employed at the outset to prevent the output from violating the time-varying constraint. Specifically, we allow the barrier limit to vary with the desired trajectory in time. Through a change of coordinates for the tracking error, we then eliminate the time dependence, therefore simplifying the analysis. We show that asymptotic output tracking is achieved without violation of the time-varying constraint, and that all closed loop signals remain bounded. The performance of the proposed control is illustrated through a simulation example. ©2009 IEEE.||Source Title:||2009 IEEE International Conference on Control and Automation, ICCA 2009||URI:||http://scholarbank.nus.edu.sg/handle/10635/69728||ISBN:||9781424447060||DOI:||10.1109/ICCA.2009.5410484|
