The pitch control system has a profound impact on the development of wind energy, and yet delay or non-minimum phase can weaken its performance. Thus, there is strong incentive to enhance technology in order counteract negative effects unidentified delays characteristics. To reduce complexity parameter-tuning process improve performance system, this paper, we propose novel method for turbine an...

In this empirical study, results show that recently developed software pitch-trackers can be as fast as some current commercial hardware pitch-trackers. Since latency was the most crucial factor in the performability of the ZETA system, comparative analyses were made of the ZETA and the AXON interfaces, as well as the fiddle~ object, a real-time audio analysis tool in the Opcode’s MAX/MSP envir...

Unmanned Aerial Vehicle (UAV) is inherently an unstable system and this necessitated the need of an external controller to stabilize and to control it. In this paper presents the exploration into the simulation, design and analysis of two autopilot schemes: (1) a fuzzy-PID controller and, (2) hybrid PID-Fuzzy controller for controlling pitch plane dynamics of an aircraft. The modeled fuzzy logi...

PURPOSE To evaluate any correlation between various foot angles and their respective American Orthopaedic Foot and Ankle Society (AOFAS) scores for pain, and the effectiveness of a medial arch orthosis. METHODS 81 children with bilateral symptomatic flatfoot were randomised into orthosis (n=55) and control (n=26) groups. The orthosis group consisted of 33 male and 22 female patients aged 36 t...

This work proposes a convex optimization-based framework for the trajectory planning and tracking of quadcopters that ensures continuous-time safety guarantees. Using convexity property B-spline curves differential flatness quadcopters, second-order cone program is formulated to generate an optimal nominal respects state input constraints, including position, linear velocity, angle, angular thr...

This paper develops a fault diagnosis (FD) and fault-tolerant control (FTC) of pitch actuators in wind turbines. This is accomplished by combining a disturbance compensator with a controller, both of which are formulated in the discrete time domain. The disturbance compensator has a dual purpose: to estimate the actuator fault (which is used by the FD algorithm) and to design the discrete time ...
