Test model for the derivative block

Buildings.Controls.OBC.CDL.Reals.Validation.Derivative

Information

Validation test for the block Buildings.Controls.OBC.CDL.Reals.Derivative. The model integrates a time varying signal, and the differentiates this integrated signal. Hence, the output der1.y matches the non-integrated signal intWitRes.u, within a small approximation tolerance.

The instance der1 uses a varying input for T which controls the accuracy of the derivative approximation. At the start of the simulation, T is small and hence the output der1.y matches the signal intWitRes.u well. As expected, the approximation error increases with increasing der1.T.

The instance der2 uses a gain of 2, and it initializes the output to 0. Hence, there is a fast transient at the beginning, and afterwards the output matches der1.y = der2.y / 2.

Validation test for the block Buildings.Controls.OBC.CDL.Reals.PID.

This model validates setting the initial state of the controller to a specified value.

The model sets the initial values xi_start=0.25 of the integrator for both instances of the controller. For the instance limPID, it also sets the initial value of the state of the derivative block xd_start=-0.5. The derivative block obtains as an input signal the value u=-0.5 because the set point weight for the derivative action is wd=0. Therefore, an initial state of x(t₀)=-0.5 causes the state of the derivative block to be at steady-state, because dx(t)/dt = (u - x)/T.
