Universal voltage conveyors in fractional-order filter design

2016 39th International Conference on Telecommunications and Signal Processing (TSP), 2016
In this paper voltage-mode fractional-order low- and high-pass filters using universal voltage conveyors are presented. The assumed order of the filters is (1 + α), where 0 < α < 1. The proposed structures use the continued fraction expansion approach and hence the fractional-order transfer functions of the filters are approximated by integer-order ...

Nonlinear Fractional-Order PID with Fractional-Order Filter Controller for Quadrotor Robot

Unmanned Systems
This paper presents a novel nonlinear fractional-order proportional-integral-derivative (NFOPID) controller with a fractional-order (FO) filter for a quadrotor. The proposed controller incorporates an FOPID structure with nonlinear gain and a fractional filter to enhance the system’s control performance.

Fractional Order Extended Kalman Filter for Attitude Estimation

2019
Attitude estimation is one of the core frameworks for a vehicle navigating with the help of inertial sensors such as accelerometer, gyroscope and magnetometer. Measurements obtained by these sensors are fused together to obtain vehicle attitude in the form of roll, pitch and yaw angles.

Adjustable Filter With Fractional-Order Element

2018
This paper deals with fractal-order frequency filter, its design methods and practical use. The proposed filter consists of operational transconductance amplifiers (OTAs), adjustable current amplifier (ACA), dual-output current follower (DO-CF) and fractional-order capacitor (FOE).
