This paper presents a comparative assessment of feed-forward schemes in hybrid control schemes for anti-swaying and trajectory tracking of a double-pendulum-type overhead crane (DPTOC) system. A nonlinear DPTOC system is considered and the dynamic model of the system is derived using the Euler-Lagrange formulation. To study the effectiveness of the controllers, initially nominal characteristics following...
This paper presents investigations into the development of hybrid control schemes for sway suppression and rotational angle tracking of a rotary crane system. A lab-scaled rotary crane is considered and the dynamic model of the system is derived using the Euler-lagrange formulation. To study the effectiveness of the controllers, initially a collocated proportional-derivative (PD) controller is developed...
This paper presents investigations into the implementation of infinite impulse response (IIR) Low pass filter techniques for anti-sway control of a gantry crane system. A lab-scale gantry crane is considered in the experimental work. An unfiltered bang-bang input voltage is used to determine the characteristic parameters of the system for design and evaluation of the low pass filtering techniques...
This paper presents investigations into the implementation of input shaping schemes for anti-sway control of a gantry crane system. A lab-scale gantry crane is considered in the experimental work. An unshaped bang-bang input voltage is used to determine the characteristic parameters of the system for design and evaluation of the input shaping schemes. The input shaping schemes with different derivatives...
