With the development of technology and economy, the use of solar photovoltaic supports is becoming more and more widespread and the usage of solar pv is becoming larger and larger. In the application of solar photovoltaic support, direct fixation is necessary. At the same time, there is also a focus on the control of solar photovoltaic support inverter.

When installing solar photovoltaic bracket, installation Angle, orientation, location, and the quality requirements and load requirements, arrangement and spacing are basic parameters, such as generally require Angle is equal to or close to install local latitude, south toward the appropriate for, location is the ground or roof.

Solar photovoltaic bracket installation quality requirements is to use life to amount to mark, at the same time to conform to the requirements of the wind load and snow load, earthquake, can be combined with local sunshine condition to select the order, to ensure that the effect of solar photovoltaic bracket to be able to give full play to.

With respect to solar photovoltaic stents, it is a strong coupling and time-varying nonlinear system because of its own power electronics. When the so-called photovoltaic stents control the inverter with linear control, the mathematical model of the inverter must be extracted and linearized.

In these processes, a large number of approximations and simplifications must be taken, and the mathematical model is greatly deviated from the actual system. Therefore, a nonlinear control method has been developed, which plays an extremely important role in the control of the inverter of solar photovoltaic stents.
