For the tiltwing UAV which i am currently designing, i am going to use a PID controller which i will develop in MATLAB. I want to determine the most optimum value for the 'P' parameter (proportional control part) of the PID controller. How best can i get this done, even using analytical techniques on paper. Or, do you know of any sources i can look into in order to get the results i seek.
Dear Harald Kirchsteiger
Optimum in terms of tuning the controller in order stabilize pitching moments in flight
you can use PID tuner in MATLAB
command >> pidTuner(sys)
look at the following link

Dear Harald Kirchsteiger ,
It will have integral and derivative controllers as well
Mohsen Rezaei , I will look into it in Matlab as well.
I will also attempt the mathematical (analytical) approach
For Analytical Approach, you can also use Ziegler–Nichols Tuning Rule Based on Critical Gain. It will be explained completely in the following book,
Modern Control Engineering, 5th edition, Chapter 8
Written by K.Ogata
Several techniques can be used to achieve this goal. Among of them, we can find the algorithms based on classical tuning techniques using the linear model of the UAV. However, these approaches are sensitive to disturbances and parametric variations of the UAV and thus do not lead to optimal performance.
So, you can also use as a solution methaheuristic algorithms for the optimal tuning of the PID parameters. In the literature, one can find several works in this domain such as those using GA, PSO, Bat algorithm and others which can be consulted.
Abdelghani Chelihi , Harald Kirchsteiger , Mohsen Rezaei , Thank you for your responses, i implementing your suggestions as i work on my design
