## Buildings.Fluid.Actuators.BaseClasses.Examples.EqualPercentageDerivativeCheck

### Information

This example checks whether the function derivative is implemented correctly. If the derivative implementation is not correct, the model will stop with an assert statement.

Extends from Modelica.Icons.Example (Icon for runnable examples).

### Parameters

Type | Name | Default | Description
--- | --- | --- | ---
Real | R | 50 | Rangeability
Real | delta | 0.01 | Value where transition occurs
Real | l | 0.001 | Leakage

### Modelica definition

model EqualPercentageDerivativeCheck extends Modelica.Icons.Example; parameter Real R = 50 "Rangeability"; parameter Real delta = 0.01 "Value where transition occurs"; parameter Real l = 0.001 "Leakage"; Real x; Real y; initial equation y=x; equation x=Buildings.Fluid.Actuators.BaseClasses.equalPercentage(time, R, l, delta); der(y)=der(x); assert(abs(x-y) < 1E-2, "Model has an error"); end EqualPercentageDerivativeCheck;
