5. CONCLUSIONS The conventional method of water pumping was very primitive in its capabilities in term of speed control. As more and more industries try to make there production line highly productive and profitable even a minute error in the quantity of liquids in packaged products can make a huge difference in the profit margin. Thus we require a more precise control over the rate of flow of liquids in such cases. As our country is facing lot of deficiency in power its has become a great concern. This has motivated the ministry of new and renewable energy sources division of India to invest more on the deployment of renewable energy resources in the country. Thus the inclusion of solar energy will promote the use of renewable energy for driving the motor. The advantages and desirable features of both zeta converter and BLDC motor drive has contributed in designing a simple, efficient, cost effective and reliable water pumping system based on solar PV energy. Simulation results using MATLAB/Simulink and experimental performances were examined to demonstrate the working of the water pumping system. The design of zeta converter was studies and demonstrated using a prototype. A better control scheme for the BLDC motor was also studies and demonstrated using a prototype. In addition the design of SPV array was also studied.

Figure 20: Set speed & Actual speed
Figure 21: Set speed & Actual speed Figure 20 shows the set speed as 1060rpm and the PI controller tunes the speed of the BLDC motor to reach 1060rpm. In Figure 21 shows the PI controller has tuned the system so that the actual speed is very much close to the set speed of 1120rpm.
