![]() Location by designing an appropriate control matrix (K), then the desired output can be obtained. If the poles of the system can be placed in the desired The characteristic equation: the determinant of the matrix. ![]() Poles of a closed-loop system can be found from We are currently copying these files manually into our ArduPilot fork to update the custom flight mode.Recall from the State-Space Tutorial page, we can use a "pole placement" technique to obtain the desired output. With the Simulink Coder a C++ class (three files) can be generated from the template. These outputs are defined as inputs in the new ArduPilot flight mode. The user can then implement any controller (rate controller, position controller, position controller or combinations thereof) in Matlab/Simulink based on these input variables.įinally, the Matlab/Simulink template provides an output for the servos/motors and an output for logging. ![]() Then there is a Matlab/Simulink template, which also has these structs defined as input variables. In ArduPilot there is a new flight mode, which grabs target inputs (stick inputs and waypoints) and measured values (from the state estimator) and stores them in two structs. Roughly speaking, the interface is structured as follows: Some work would be needed to merge it, but actually it’s not that elaborate either. Is there any interest in merging such an interface? I have a question that is probably more directed to the developers. I definitely know that the compilation process was not contained within the matlab/simulink environment. I don’t know the details but it sounds like pictures to code generated either the cpp or object file that they then included into the compilation process using the standard ardupilot compilation tools. Sounded like they had to map the appropriate inputs and outputs to their controller in simulink. I know a group that essentially replaced the attitude controller in the ardupilot software using the pictures to code feature in matlab/simulink. What does your control system cover? taking the sensor input and pilot commands and calculating the outputs to the motors? or does it go further than that. I would like to incorporate this control system into the vehicle’s current system, but I have limited experience with C++ so I would like to use one of Simulink’s code generation tools to make this easier. I have designed a novel control system in Matlab/Simulink. I apologize if I picked the wrong category for this I am anticipating this process will require generating code and then consulting with someone more knowledgeable in programming to incorporate into our existing control system, but I want to make sure that any code I am able to generate automatically is usable. My concern is that if it is meant for use specifically with the px4 control system I may not be able to generate useful code from it. This package is designed for Pixhawk, but specifically mentions PX4, although it seems to use this interchangeably with Pixhawk. This package seems to be designed for ArduPilot Mega 2.0 and not Pixhawk. ![]() I found these and I would appreciate help with determining if either would be useful to me: There is a lot of documentation from matlab/simulink on these tools, but my understanding is that I need a hardware support package to make the automatic code generation work. I am working with a vehicle which currently uses ArduPilot (ArduRover) and a Pixhawk 2.1.
