abstract: this paper presents dynamic modelling and control of a linear prismatic series of elastic actuator. the capability of generating large torques is why this actuator is increasingly used in human-assistive robotic systems. due to having human in the loop, the actuator requires precise control. a fractional pid controller known for its improved performance is used for the control, due to...

Abstract In this paper, load frequency control is performed for a two-area power system incorporating high penetration of renewable energy sources. A droop controller type 3 wind turbine used to extract the stored kinetic from rotating masses during sudden disturbances. An auxiliary storage applied achieve effective response. The coot optimization algorithm (COA) allocate optimum parameters fra...

This paper presents the application of a direct Fractional Order Model Reference Adaptive Controller (FOMRAC) to an Automatic Voltage Regulator (AVR). A direct FOMRAC is a direct Model Reference Adaptive Control (MRAC), whose controller parameters are adjusted using fractional order differential equations. Four realizations of the FOMRAC were designed in this work, each one considering differen...

This study proposes a novel modified grey-wolf optimization algorithm (MGWOA) to enhance power system stability. The stabilizer and static synchronous series compensator (SSSC) are used as damping controllers. Additionally, fractional-order PID (FOPID) controller is handle the nonlinearities thus achieve better performance. control parameters tuned using proposed MGWOA method which has been ver...

Continuum robots are the behavioral extension of hyper-redundant usually inspired by living biological organs. These outperform their rigid counterparts regarding high flexibility, dexterity, and most importantly safe interaction. On flip side, they kinematically redundant, highly nonlinear, multi-input, consequently, controlling remains a complex challenging task. To this end, paper proposes F...

An intelligent control strategy is proposed in this paper which suggests the Optimum Power Quality Enhancement (OPQE) of grid-connected hybrid power systems with solar photovoltaic, wind turbines, and battery storage. Unified Conditioner Active Reactive (UPQC-PQ) designed Atom Search Optimization (ASO) based Fractional-order Proportional Integral Derivative (FOPID) controller Hybrid Renewable E...

Bu çalışmada, klasik oransal-integral-türev (PID) kontrolörlerin gelişmiş hali olan kesir dereceli (FOPID) kontrolörlerden faydalanılarak basitleştirilmiş gaz türbinli bir santral modeli için denetlemenin hassas şekilde yapılabilmesi sağlanmıştır. Klasik PID kontrolörler (denetleyiciler) üç parametre içerirken, beş içerir. Parametre sayısının fazla olması daha yapılabilmesine olanak sağlar, anc...

One of the most popular controllers for automatic voltage regulator (AVR) in maintaining level a synchronous generator is fractional-order proportional–integral-derivative (FOPID) controller. Unfortunately, tuning FOPID controller challenging since there are five gains compared to three conventional proportional–integral–derivative (PID) Therefore, this research work presents variant marine pre...

Interacting The highest storage capacity of a circular tank makes it popular in process industries. Because the varying surface area cross-sections tank, this two-tank level system has nonlinear characteristics. Controlling flow rate liquid is one most difficult challenges production process. This proposed effort critical preventing time delays and errors by managing fluid level. Several schola...
