The article investigates the problem of estimating state a time-varying system with linear measurement model; in particular, considers case where number measurements available can be smaller than states. In lieu batch least-squares approach—well-suited for static networks, sufficient could collected to obtain full-rank design matrix—the proposes an online algorithm estimate possibly by processi...

This paper designs an Optimized Adaptive Combined Hierarchical Sliding Mode Controller (OACHSMC) for a time-varying crane model in presence of uncertainties. Uncertainties have always been one of the most important challenges in designing control systems, which include the unknown parameters or un-modeled dynamics in the systems. Sliding mode controller (SMC) is able to compensate the system in...
