This paper proposes an approach for the minimum time swing upof a rotary inverted pendulum. Our rotary inverted pendulum is supported bya pivot arm. The pivot arm rotates in a horizontal plane by means of a servomotor. The opposite end of the arm is instrumented with a joint whose axisis along the radial direction of the motor. A pendulum is suspended at thejoint. The task is to design a contro...

Visual impairments are not the core symptoms in PD, but gain in significance when accompanied by exacerbation of the primary symptoms, since visual impairments reduce compensation and adaptation the patient to motor disturbances. Most frequent complaints include fuzzy vision, photophobia, asthenopia (with eye fatigue, often accompanied by headache and blurred vision). Patients with PD often fin...

The network and plant can be regarded as a controlled time-varying system because of the random induced delay in the networked control systems. The cerebellar model articulation controller CMAC neural network and a PD controller are combined to achieve the forward feedback control. The PD controller parameters are adjusted adaptively by fuzzy reasoning mechanism, which can optimize the control ...

This study develops and implements a design of the Fuzzy Proportional Integral Derivative with filtered derivative mode (Fuzzy PIDF) for Load Frequency Control (LFC) two-area interconnected power system. To attain optimal values proposed structure’s parameters which guarantee best possible performance, Bees Algorithm (BA) other optimisation tools are used to accomplish this task. A Step Perturb...

In the present study, an Enhanced SSA (ESSA) has been proposed where parameter of technique, which balances exploration and exploitation phases, modified. Additionally, variable scaling factor is engaged to regulate salp’s position during search procedure minimize random movement salps. To demonstrate effectiveness enhanced (ESSA), a set multimodal test functions are engaged. The statistical ou...

ABSTRACT One of the challenging issues to consider in balancing a two-wheeled robotic machine (TWRM) is when the load carried by the machine is changing position along the vehicle intermediate body (IB). An issue of interest in this case is the resulting impact on the system behaviour due to changing position of the load. Further complications arise with changing the size of the load. This work...

objectives to explore the effect of a selective 10-week corrective exercise with an emphasis on gait training activities (gta) on the number of falls (nofs), fear of falling, functional balance, timed up and go (tug) test among pd patients. background posture instability and unsteady gait disorders in parkinson’s disease (pd) usually contribute to fall-related fractures. fall-related trauma in ...

A three-term (proportional plus integral plus derivative, PID) fuzzy logic controller (FLC) algorithm have been and continue to be a very active and fruitful research field since early pioneered work on fuzzy controller. In this study, we propose taxonomy of various methods to design three-term FLC. Two applications representing second-order systems and third-order systems were used to analyze ...

A novel approach for solving fuzzy model-based stability problems via evolutionary computation (EC) is presented. Gain scheduling problem of a multi-model fuzzy system that satisfies the Lyapunov stability criteria is solved. The generalized eigenvalue problem (GEVP) can be directly introduced to EC in searching positive definite (PD) or positive semi-definite (PSD) matrices, by making a penalt...

Biogeography-based optimization (BBO) is an evolutionary algorithm (EA) based upon the models of biogeography, which describe the relationship between habitat suitability and the migration of species across habitats. In this work, we apply BBO to the problem of tuning the fuzzy tracking controller of mobile robots. This is an extension of previous work, in which we used BBO to tune a proportion...
