Adaptive Control Based on Incremental Hierarchical Sliding Mode for Overhead Crane Systems
نویسندگان
چکیده
Incremental hierarchical sliding mode control (IHSMC) methodology involves 2n−2 sign switches of controller parameters for an underactuated system with n subsystems. Too many sign switches trouble parameter tuning. This paper presents an adaptive control design approach based on IHSMC methodology for overhead crane systems with 2 subsystems with only 1 sign switch. The system stability is proven by Barbalat’s lemma and Lasalle’s invariance principle in the sense of Lyapunov theory. Simulation results illustrate the feasibility of the presented method by transport control of overhead crane systems.

Energy Optimization of Under-actuated Crane model for Time-Variant Load Transferring using Optimized Adaptive Combined Hierarchical Sliding Mode Controller
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...

In recent years, underactuated nonlinear dynamic systems trajectory tracking, such as space robots and manipulators with structural flexibility, has become a major field of interest due to the complexity and high computational load of these systems. Hierarchical sliding mode control has been investigated recently for these systems; however, the instability phenomena will possibly occur, especia...
