A new approach to control, stabilization and disturbance rejection of attitude subsystem quadrotor is presented in this article. Analytical method used tune conventional structure PID controller. SISO implemented for control achieve desired objectives. The performance the designed evaluated through time domain factors such as overshoot, settling integral error index, robustness. comparison done between controller back-step applied main model quadrotor. results simulation show effectiveness scheme.
Bedrocks of engineering projects are commonly affected by freezing-thawing (F-T) process in mountainous areas. Consequently, determining the degradation rate rocks due to F-T cycles cold areas has a key role project design and its safety level. In this research, influence on some physico-mechanical characteristics three main Angouran mine (limestone, amphibolite-schist, mica-schist) was investigated. For purpose, unconfined compressive strength (UCS), Schmidt hardness, dry density, water...
In the primary and final designs of projects related to rock mechanics engineering geology, one key parameters that needs be taken into account is intact elastic modulus (E). To measure this parameter in a laboratory setting, core samples with high-quality costly tools are required, which also makes for time-consuming process. The aim study assess effectiveness two meta-heuristic-driven approaches predicting E. models proposed paper, based on integrated expert systems, hybridize adaptive...
Generally, longwall mining-induced stress results from the relaxation due to destressed zone that occurs above mined panel. Knowledge of induced is very important for accurate design adjacent gateroads and intervening pillars which helps raise safety productivity mining operations. This study presents a novel time-dependent analytical model determination investigates coefficient concentration over gates pillars. The developed based on strain energy balance in incorporated rheological...
In this study, an enhanced short‐time Fourier transform (STFT)‐based jamming mitigation system which employs several windows to increase time–frequency ( t–f ) plane resolution is proposed. A technique for employing near‐optimum also It observed that selection of these leads increasing the representation. An infinite impulse‐response notch filter employed removal process. Performance proposed method evaluated by a set measured global positioning data. compared with conventional STFT‐based...
Deformation modulus is the important parameter in stability analysis of tunnels, dams and mining structures. In this paper, two predictive models including Mamdani fuzzy system (MFS) multivariable regression (MVRA) were developed to predict deformation based on data obtained from dilatometer tests carried out Bakhtiary dam site additional collected longwall coal mines. Models inputs considered be rock quality designation, overburden height, weathering, unconfined compressive strength,...
