DSP Based Slide mode Control for Photovoltaic system

Project Title

DSP Based Slide mode Control for Photovoltaic system

Project Area of Specialization Electrical/Electronic EngineeringProject Summary

One of the independent sources in nature is Sunlight. It is available to everyone for a 12-14 hours duration in a day. Currently, sunlight is one of the main sources of electricity, but the output of the PV panels has a nonlinearity problem. Voltage fluctuation occurs due to variations in light intensity and individual temperature on every solar cell, which causes circuitry damage and overheating and hence decreases in the efficiency of the solar cell.

our main objective is to catter the following problems that occur in a solar pannel.

•Nonlinearity effect the efficiency

•Unintelligent soalr panel

•Circuit damages

•Overheating 

Project Objectives

Our objective is to cater the nonlinear behavior of solar energy and to get regulated DC output we are going to use the nonlinear SMC technique by using DSP kit which have following attributes

Strong capability to reject unacceptable disturbance.

Provides less steady state error.

Found more suitable for non-linear system than PID control technique

Potential to offer robustness in sliding mode phase.

Project Implementation Method

first there is a DSP kit for programming. In this DSP kit we will do programming. After that we will extract Maximum power point (MPPT) by using incremental cinductance technique. after that there is a Boost Converter that will stepup the DC voltage and then we have a controller(slide mode controller) and give this output to the input gate of MOSFET.

•Photovoltaic generator which converts solar energy into electric energy,

• DC-DC converter exploiting the generated voltage by the PVG to feed the load voltage,

•Digital controller that drives the converter commutations according to the MPPT capability,

• Load.

Benefits of the Project

Only product to cater non linearity

One time investment for maximum energy

Linear energy without fluctuation and overheating

Maximum Power from solar pannel

Technical Details of Final Deliverable

we will deliver the software and Hardware of the prohect. we will implement out project on matlab simulink.

we will learn SMC base solar cell is better than PID base Controller in non linearlity behaviour.
