Overhead Crane is a heavy equipment which is very much found in various industries, factories, and workshops that are used to transport material. In general, controlling the Overhead Crane is operated by using a Push Button that is hung together with a cable on the top frame of the Overhead Crane. in this case, humans must also be able to maintain a distance when controlling Overhead Cranes that are working to transport memterials to avoid the use of Overhead Cranes. To provide security and comfort in the use of Overhead Cranes, the authors designed an Overhead Crane controller using Arduino based cable and wireless. The design of Overhead Crane control using a cable consists of several series of Push Button arranged in a plastic box and then hung on the side of the Girder Crane. for the input foot the Push Button is given a voltage 12 VDC, while the output of the Push Button is connected with contact points of the Relay 12 VDC to execute electrically mechanical Overhead Crane. While the Overhead Crane control design using wireless consists of several components, including: Arduino Mega 2560 which is combined with USB Host Shield. Bluetooth csr 4.0 Dongle is connected to the USB Host Shield port for data communication media between Arduino Mega 2560 with Bluetooth Joystick PlayStation 3 (PS3). The signal pin of the Relay modules is connected with Arduino Mega 2560 pins according to the program designed. Contact NO points Relay modules are connected with 12 VDC Relay point contacts to execute electrical mechanical Overhead Crane.

A comparative study about two models, Muskingum and integrator-delay (ID) models, for canal control is presented. The former is a simplified hydrological model which is very simple and extensively used in hydraulic engineering for simulation and prediction. The latter is also a model with physical meaning and is widely used for irrigation canals control. Due to a lack of general awareness of Muskingum prediction model in regulation from the control community, authors present this comparative study with the ID control model. Both models have been studied and analyzed for control purposes. This study has been carried out and validated in a real irrigation canal, at Aghili irrigation district in Iran, using two traditional control approaches, PID with feedback and predictive control. The results demonstrate the advantages and drawbacks of both models, showing the benefits and limitations of using the widespread Muskingum model among the hydraulics scientific community for control design.

Abstract Many modern day applications involve transport of objects suspended through cables such as in overhead cranes or landing of rovers on the Martian surface. Any undesired oscillation of the payload has the potential risk of instability and the problem of damping such oscillation and stabilizing the payload at a desired length is the control objective of this paper. The system is modeled as a variable length pendulum (VLP) which comprises of a payload suspended via a string wrapped around a pulley. The length of the pendulum is varied using clockwise/counterclockwise rotation of the pulley through torque applied by a motor. For a known payload mass, a nonlinear control design is first presented that guarantees asymptotic stability of the desired equilibrium with limited state measurements. The design is then modified for it to handle significant uncertainty in payload mass. The effectiveness of both the designs are validated in simulations.
