In this paper a method for recursive Takagi Sugeno fuzzy model identification using weighted recursive least squares with optimal initial condition of the parameters based on particle swarm optimization (PSO) applied to static nonlinear and time-variant delay systems is proposed. For this approach, it is used a priori knowledge of the nonlinearities of interest in the system to improve the quality...
Autonomous robots play a pivotal role in improving productivity and reducing operational costs. They excel at both precision and speed in repetitive jobs and can cooperate with humans in complex tasks within dynamic environments. Self-localization is critical to any robot that must navigate or manipulate the environment. To solve this problem, a modular localization system suitable for mobile manipulators...
This paper presents the procedures for the wind speed measurement using ultrasonic transducers. The wind speed measurement is based on the time-of-flight (ToF) ultrasonic estimation that has been estimated using the Extended Kalman Filter (EKF) algorithm. For this purpose it was developed the dynamic system model in state space and was analyzed the convergence of the EKF algorithm. Simulation results...
In this paper we propose an algorithm for high-resolution, joint azimuth, elevation and polarization estimation using polarimetric arrays of arbitrary geometry. The array elements may be placed on a planar or conformal surface and all the array imperfections are considered jointly. In particular, we focus on real-world arrays with imperfections. The Crameacuter-Rao Lower Bound (CRLB) for polarimetric...
In this paper we propose azimuth and elevation angle of arrival estimation algorithms for arbitrary array configurations. The proposed algorithms extend the Polynomial Rooting Intersection for Multidimensional Estimation (PRIME) and statistically efficient Modified Variable Projection (MVP) algorithms to arbitrary sensor array configurations without explicit knowledge of the steering vector. The proposed...
