Swing-Free Manoeuvre Controller for Rotorcraft Unmanned Aerial Vehicle Slung-Load System Using Echo State Networks

Abstract:

There is a growing interest in developing Rotorcraft Unmanned Aerial Systems (RUAS) with advanced onboard autonomous capabilities. RUAS is a very versatile vehicle and its unique flying characteristics enable it to carry loads, hanging in wires underneath it. This suspended load alters the flight characteristics of the vehicle. In this paper, an anti-swing manoeuvre controller for a rotorcraft unmanned aerial system with an attached suspended load (slung-load) is proposed. The presented architecture is powered by Echo State Networks (ESN) that enables simple modeling of the controller and outperforms linear techniques in terms of robustness to unmodelled dynamics and disturbances. The external load behaves like a pendulum; this can change the natural frequencies and mode shapes of the low frequency modes of the RUAS. The technique chosen to solve the problem is to achieve both robust performance and computational efficiency. Reservoir Computing (RC) is an alternative to gradient descent methods for training Recurrent Neural Networks (RNN), which represent a very powerful generic tool, integrating both large dynamical memory and highly adaptable computational capabilities. ESN is a type of reservoir computing; the advantage lies in the ability to overcome the difficulties in RNN training, it is conceptually simple and computationally inexpensive. It has been demonstrated that a model and controller design using ESN may be developed. ESN performs well to control unknown nonlinear systems.

  1. You actually make it appear really easy together with your
    presentation but I to find this matter to be actually one
    thing that I believe I’d never understand. It sort of feels too
    complex and very wide for me. I’m taking a look
    forward to your next publish, I will try
    to get the dangle of it! Najlepsze escape roomy

  2. The next time I read a blog, Hopefully it does not fail me as much as this particular one. I mean, Yes, it was my choice to read, however I really thought you would have something interesting to talk about. All I hear is a bunch of crying about something that you could fix if you weren’t too busy looking for attention.

  3. Howdy! I could have sworn I’ve visited this web site before but after looking at a few of the posts I realized it’s new to me. Anyhow, I’m definitely delighted I stumbled upon it and I’ll be book-marking it and checking back regularly.

  4. I blog often and I truly appreciate your content. This great article has truly peaked my interest. I will book mark your blog and keep checking for new details about once per week. I subscribed to your Feed as well.

  5. I’m amazed, I have to admit. Seldom do I encounter a blog that’s both educative and amusing, and without a doubt, you’ve hit the nail on the head. The problem is an issue that too few people are speaking intelligently about. I am very happy that I found this in my search for something concerning this.

  6. I have to thank you for the efforts you have put in penning this blog. I’m hoping to view the same high-grade blog posts from you in the future as well. In fact, your creative writing abilities has motivated me to get my own site now 😉

  7. I blog quite often and I truly appreciate your information. Your article has really peaked my interest. I’m going to take a note of your blog and keep checking for new information about once per week. I subscribed to your RSS feed as well.

  8. Aw, this was a really good post. Finding the time and actual effort to create a superb article… but what can I say… I put things off a whole lot and never seem to get nearly anything done.

  9. As the native inhabitants grew, a faculty bond was issued, permitting for the development of a new school, named Central
    School, at 826 Chestnut Road. As an illustration in Central Asia, China acquired shares in firms that exploit gas
    fields (MangistauMunaiGas and KazMunaiGas E & P); China acquired
    the rights to take advantage of fields in Turkmenistan when different
    international locations are still struggling to acquire such
    rights; China financed and helped in the construction of
    the pipelines operating from the fields (CNPC, China
    Petroleum Pipeline Bureau and China Petroleum Engineering and Building Company); and
    China purchases the fuel manufacturing.
