In "frestimate(modelname,op,io,in)", the linearization I/O io(1) seems to be a non-double signal. All input and output IOs are required to be on double signals.

i am currently tryingto simulate a quadcopter model that i found online. i edited few perameters and was trying to tune it afterwards to get it to stabilise.

As it opens the PID tuner, it cannot linearise the model so i used systems identification to simulate the model. the problem is when i try to do that, i get the following error.

In "frestimate(modelname,op,io,in)", the linearization I/O io(1) seems to be a non-double signal. All input and output IOs are required to be on double signals.

this happens when i try to tune the pitch or roll PIDs.

i got the model from the follwing link.

does anyone know what this means or how could it be fixed.

Thanks all.
