Revolute control techniques of USBM simplified model

Universal Stretch and Bending Machine (USBM) is a combination of Stretch Machine and Bending Machine which are used in car door sash production. The main purpose of combining these two machines is to reduce the number of machines, space utilization and increase productivity. This paper presents the design and modeling for revolute control techniques of USBM simplified module. Conventional proportional-integral-derivative (PID), Linear Quadratic Regulator (LQR), and proportional-derivative (PD)-type Fuzzy Logic Controller (FLC) are proposed to control the angular position of the revolute model. Simulation is implemented in SIMULINK/MATLAB and the results of the response of the system with the controllers are presented in time domains. The performances of the control schemes are assessed in terms of input tracking capability and time response specifications. Finally, a comparative assessment of the control techniques is presented and discussed.
