Veronte Data

The first part of the Veronte tab is the identification of the autopilot. Here is defined the name of the configuration Vehicle Name. It is possible to control more than one air with the same ground, just change the address of the autopilot to 2, 3 and then it will be detected by the system. The Encryption can be activated from this panel by clicking on the shield icon.

SU / US Matrix

SU & US are inverse matrices which contain the relationship between actuators and control channels. This relationship should be completed in order to define the influence of each control channel in each control actuator. In the SU matrix, the Control channels are positioned in the columns and the Actuators in the rows. For example, in the following matrices, Actuators 1 and 2 control the Rolling, Actuator 3 the Flaps and so on.


SU Matrix Values example


US Matrix Values example

U is  a vector which contains the control outputs of the system. These values are not real controls, but fictitious variables that are used in the controller algorithm. What is really applied to the actual system are the servo movements (actuators) which are in the S vector. The relation between this two vectors is depicted by the SU matrix.

The option of having a configurable SU matrix allows Veronte to control any type of vehicle, independently of how its control surfaces are. Just by introducing in this matrix the values that map the control outputs to the servo movements the control of the platform is possible.

Let’s consider an example to clarify what has been said above. Imagine that the aircraft to control has no tail, so the typical aileron and elevator movement is done with the same control surface, for example, the elevons. Inside the controller algorithm, the program works with elevator and aileron deflection separately, as in a conventional aircraft, but the outputs of the controller have to be adapted to the actual configuration of the aircraft, and here is where the SU matrix is used.

If the relation of the elevon movement with the aileron and elevator deflection is as shown in the next expression,


the SU matrix which provides the actuator deflection from a set of output controllers is as represented in this figure.


In addition to the SU matrix, it is also possible to set in Veronte Pipe the inverse matrix, US. This one is not as important as the previous matrix but has also its functions. Normally, this matrix is used when there is a radio controller connected to the system because the pilot stick movements are values of the S vector, and in the case that these values have to be changed to controller commands for the algorithm, that task is performed with the US matrix.
