The main purpose of this study is to compare two different feedback controllers for the stabilization of quiet standing in humans, taking into account that the intrinsic ankle stiffness is insufficient and that there is a large delay inducing instability in the feedback loop: 1) a standard linear, continuous-time PD controller and 2) an intermittent PD controller characterized by a switching fu...

Mathematical modelling of the simplest Takagi−Sugeno fuzzy Two-Input Two-Output (TITO) Proportional-Integral/Proportional-Derivative (PI/PD) controller is presented in this paper. model PI/PD proposed using Algebraic Product (AP) t-norm, Bounded Sum (BS) t-co-norm and Center Gravity (CoG) defuzzifier. The inputs are fuzzified by sets having L <math id="mathml_M2"...

An adaptive fuzzy PID controller with gain scheduling is proposed in this paper. The structure of the proposed gain scheduled fuzzy PID (GS_FPID) controller consists of both fuzzy PI-like controller and fuzzy PD-like controller. Both of fuzzy PI-like and PD-like controllers are weighted through adaptive gain scheduling, which are also determined by fuzzy logic inference. A modified genetic algo...

As an option to deal with insulin-dependent disease, a recently commuted PD control strategy is designed and carefully analyzed for different clinic diabetic patients. This controller approach mainly conceived stabilize the glucose blood concentration in patient around its basal value; hence, avoiding extreme situations such as hypoglycemia hyperglycemia. receives two inputs tuned actuate when ...

Fractional-order controllers have gained significant research interest in various practical applications due to the additional degrees of freedom offered their tuning process. The main contribution this work is analog implementation, for first time literature, a fractional-order controller with transfer function that not directly constructed from terms Laplacian operator. This achieved using Pa...

Abstract: In control applications, most of the physical systems require a real-time operation to interface high speed constraints; higher density programmable logic devices such as field programmable gate array (FPGA) can be used to integrate large amounts of logic in a single IC. This paper presents an Experimental implementation of digital logic designs on the Altera DE2 board which presented...
