Design of PLC for Water Level Control Employing Swarm Optimization-Based PID Gain Scheduling

A design of swarm optimization-based gain scheduling PID controller for water level control is presented in this paper. The framework is implemented on Mitsubishi PLC monitored by pressure sensors with Omron SCADA package. An Ethernet built-in module is used to communicate between the front-end and field. The proposed controller is applied to regulate the speed of a DC water pump. Experimental results show fast transient response with low fluctuation on water level compared to that from non-adaptive method.
