Integrator system

First ordre system with delay

First order system

The time constant T1 of the transfer function Ipv/Ub changes with sun exposure.

The gain K1 of the transfer function Ipv/Ub rises slightly with sun exposure.

The transfer function Ipv/Ub does not depend on the solar panel angle.

The PD Controller is much faster than a P Controller.

The PD Controller is much slower than a P Controller.

The PD Controller acts like a high-pass filter and measurement noise is amplified.

P Controller as the integrator system is suffisant to remove the error of the control system.

PI controller as the the integrator system is not suffisant to remove the error of the control system.

The angle error is negligible, as the P controller is adequate for angle controlling with a integrator system.

There is an angle error which has to be removed by using a PI controller.

The PI controller is always necessary to eliminate the error of the control system even if the system is integrator.

The PI controller can not eliminate the error of the control system even if the system is integrator.

With 2 Integrator in the closed loop (Integrator System and PI Controller), the control system can easily oscillate and becomes instable.

When the gain K of the integrator system is too high.

When the system disturbances are important.

When the gain K of the integrator system is too low.
