How can I control Z position ( Altitude) of my parrot minidrones , exactly parrot mambo with Simulink? I have a problem with Ultrasonic sensor.

I have a problem with my parrot mimidrone, mambo. I want to control Altitude of the drone with Simulink project.

Because of It's system frrequency(200Hz), mambo shoots sonar at the everytime of it's system frequency(0.005s which is set to be Ts by Simulink).

So, my drone can not exactly catch it's altitude at over0.85m! (sonar can move 1.7m in 0.005s) and Drone be unstable at high altitude because of this problem.

How can I solve this problem?

How can I control the Sonar triger ferquency?

Hello. Did you solve the problem? I am looking for a solution for the exact same situatuon. Can help me?

I think that's why there is a pressure sensor available, for higher altitudes, the higher Z must be derived from the pressure. Alternative, integrate the ddz twice

Hi how can one model the pressure and ultrasonic sensor?
