Coordination Power Control Of DC Water Pump System using Dual-loop Control and Consensus Algorithm

Power control in household devices are needed to avoid trip conditions on electric current. One of the power controls is the control of the water pump. Often, water pumps installed in one house are more than one. To overcome these problems, it is necessary to design an algorithm to coordinate each of the water pumps. In this study, the Consensus algorithm is designed to coordinate the water pumps used. The algorithm is used to generate reference signals for each agent (water pump). Integral Sliding Mode Current Control (ISMCC) and PI Controller is used as local controller. ISMCC is inner-loop current controller and PI is outer-loop power controller. The simulation result shows that power response of each agent is able to follow reference signal from Consensus algorithm even though any unknown pump parameters. However, overshoot of the total power is more than 5%.
