Design of Combining Sliding Mode Controller for Overhead Crane Systems
In industries, overhead cranes are commonly employed to lift and lower materials or to move them horizontally. A combining sliding mode control method is proposed for overhead crane systems in this paper. The ideas behind the combining sliding mode are as follows. First, an intermediate variable is introduced by dividing the system states into two groups. Then, a sliding surface is defined on b...
متن کاملEnergy 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...
متن کاملDesign of Sliding Mode Controller for the 2D Motion of an Overhead Crane with Varying Cable Length
Overhead cranes are under-actuated systems. They have three outputs that need to be controlled, consisting of cargo swing angle, trolley displacement, and suspended cable length, but only two actuators: cargo lifting and trolley driving forces. The main objective of this study is to design a robust controller for an overhead crane that transfers cargo from point to point as fast as possible and...
متن کاملAdaptive Control Based on Incremental Hierarchical Sliding Mode for Overhead Crane Systems
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 prove...
متن کاملRobust Adaptive Fuzzy Sliding Mode Control of Permanent Magnet Stepper Motor with Unknown Parameters and Load Torque
In this paper, robust adaptive fuzzy sliding mode control is designed to control the Permanent Magnet (PM) stepper motor in the presence of model uncertainties and disturbances. In doing so, the nonlinear model is converted to canonical form, then, for designing the controller, the robust sliding mode control is designed to decrease the effects of uncertainties and disturbances. A class of fuzz...
