Time delay effect reduction on the wireless networked control system using an optimized FOPI-FOPD controller

Wireless Networked Control System (WNCS) is made up of an actuator, sensor, and controller that communicates through a wireless network rather than typical point-to-point cable connections. Lower maintenance costs, greater flexibility, increased safety are the main WNCS advantages, so as result, it has attracted lot researchers. Nevertheless, time delays packet losses in data transmission classified complicated problems, which impair output accuracy may influence overall system stability. Integer-Order PI-PD (PI-PD) Fractional-Order (FOPI-FOPD) controllers proposed to reduce impact control signal transmission's delay improve performance. Matlab Simulink True-time simulator used simulate WNCS, ZigBee protocol transceiving between system. Rotary Inverted Pendulum (RIP) acted controller's objective. The Grey Wolf Optimization (GWO) technique utilized evaluate best parameters. Xbee S2 modules implement process over protocol. FOPI-FOPD outperforms simulation experimental results decreasing on stability
