Abstract:
Fractional order PID (FOPID) controller is a special k ind of PID controller which it’s derivative and integral order are fractional rather than integer and has five parameters. Using this control improves the control results in accuracy and speed. Statistics show that using this controller for systems with high sensitivity is more practical and safe.Mechanical closed loop test rig acts an important role in aviation industry. Fault diagnosis in gearboxes and othercritical components of the airplane and helicopters is the most important part of this industry. More over testing rotating equipment is very important for system security verification. There are several testing techniques and manyimportant testing parameters. One of these essential factors is gearbox secu rity test technique. What’s more,mechanical closed-loop system is a very cost effective method. For financial, energy consumption and maintenancereasons, using a system with the ability of energy regeneration is suggested. In this paper mechanical close loop withenergy regeneration mechanism is used for testing the helicopter gearbox. Two kinds of controllers are used for keeping the closed-loop’s torque in the constant value. The result of paper shows the behavior of PID and FOPID controller methods in controlling torque circulating in this mechanical closed loop. Beside the overshoot and settling time is considerable
