Design and Implementation of An Intelligent Hoist Mechanism for Barrage Dam Gate Operation

Water management relies on precise control of barrage gates to regulate irrigation, flood control, and hydropower. Traditional manual and ‎simple electromechanical systems struggle with lag, unpredictable response, and energy waste under varying hydraulic loads. This paper ‎designs an intelligent hoist mechanism integrating ultrasonic and pressure sensors with rotary encoders and a hybrid Proportional Integral ‎Derivative (PID) fuzzy logic controller, simulates structural strength in ANSYS and control logic in MATLAB Simulink, and then implements Programmable Logic Controller (PLC) and Internet of Things (IoT) modules for real-time monitoring and adaptive actuation. A 4.5-meter height, 18.00 span gate weighing 30.75 tons responded smoothly, time response would vary, reaching 90% open in 608 seconds and ‎full travel in 675 seconds. Under flows from 12.60 to 283.50 cubic meters per second, the gate opening ranged from 20 to 450 centimetres, ‎with motor rotations from 490 to 8400 and speeds from 98 to 1500 RPM; power draw varied between 800 and 2200 watts. The proposed ‎system delivers energy efficiency, stable operation, and scalable performance for dynamic water regulation‎.
