  • A sliding mode control scheme is proposed for the crane. This scheme, which guarantees the asymptotic stability of the closed-loop system, has two objectives: position regulation and anti-swing control. The performance of the closed-loop system is simulated using MATLAB.

  • Sliding mode control for underactuated overhead cranes

    The control objective for overhead cranes is to achieve precise trolley positioning and payload swing elimination simultaneously, namely, [ x x ˙ θ θ ˙ ] ⊤ → [ p d 0 0 0 ] ⊤.

  • A fuzzy sliding mode control strategy for offshore container cranes is investigated in this study. The offshore operations of loading and unloading containers are performed between a mega container ship, called the mother ship, and a smaller ship, called the mobile harbor (MH), which is equipped with a container crane.

  • An adaptive sliding mode fuzzy control approach is proposed for a two-dimensional overhead crane. System linearization transforms the two-dimensional system to two independent systems: X-direction transport system and Y-direction transport system. Both the two systems are with the same dynamic model and include two subsystems: positioning subsystem and anti-swing subsystem.

  • To solve the problem, we start by determine fi, gi and hi in terms of virtual control ui from equation then we can determine the twelve real actuators. 4.2 Stabilization of the crane Usually the control objective for an overhead crane is to drive the trolley to reach the desired position while eliminating the payload swing.

  • Overhead cranes, which are known as typical underactuated systems, are extensively studied in recent years. However, many existing methods for overhead cranes are developed based on a relatively ideal model, with little consideration for persistent external disturbances, unmodeled dynamics, uncertain system parameters and so on.

  • The methodology of hierarchical sliding mode control (HSMC) covers several design methods. At first, this chapter introduces these basic HSMC methods, i.e., aggregated SMC, incremental SMC, and

  • The robust control of cranes, especially structure variable control (SVC) technique, has been studied by many researchers. Lee [7] suggested a sliding mode anti-swing control for overhead cranes designed based on Lyapunov stability theorem. Shyu [8], [9] presented a sliding mode control (SMC) to minimize swing angle and

  • Mar 22, 2013 · An overhead crane transports cargoes of various weights and volumes depending on the operation case. Friction factors characterized by damped coefficients are changeable in terms of the operating environment. In this study, an adaptive version of the sliding mode control of a crane system is developed in the case of no priori knowledge of the payload mass and damped elements. Using two inputs

  • Jul 08, 2016 · Sliding mode control, in general, requires one actuator for every control objective. Compared to the vast literature on sliding mode control, there has been little work on general theories that can be applied to underactuated nonlinear control. A sufficient condition to guarantee simultaneous robust stabilization of multiple surfaces is derived.

  • Apr 29, 2017 · In practice, overhead crane systems are widely used and the traditional control methods for a crane system usually treat it as a single pendulum system. However, when the hook mass cannot be ignored or the payload is too large, the crane system may behave more like a double pendulum system, which leads to the fact that traditional control methods are not suitable in this situation.
