چکیده

In this paper, we analyze the dynamical behavior of delayed fractional-order tumor model with Caputo sense and discretized conformable model. The is constituted group nonlinear differential equations having effector cells. First all, stability bifurcation analysis in fractional derivative studied, existence Hopf depending on time delay parameter proved by using center manifold theory. Applying discretization process based piecewise constant arguments to version gives a two-dimensional discrete system. Stability Neimark–Sacker system are demonstrated Schur-Cohn criterion projection method. This study reveals that τ h discrete-time have similar effects corresponding systems. Moreover, effect order systems discussed. Finally, all results obtained interpreted biologically, numerical simulations presented illustrate support theoretical results.

Chaotic dynamics and synchronization of fractional order PMSM ‎system

‎In this paper, we investigate the chaotic behaviors of the fractional-order permanent magnet synchronous motor (PMSM) system. The necessary condition for the existence of chaos in the fractional-order PMSM system is deduced and an active controller is developed based on the stability theory for fractional systems. The presented control scheme  is simple and flexible, and it is suitable both fo...

SCA based Fractional-order PID Controller Considering Delayed EV Aggregators

The EVs battery has the ability to enhance the balance between the load demand and power generation units. The EV aggregators to manage the random behaviour of EV owners and increasing EVs participation in the ancillary services market are employed. The presence of aggregators could lead to time-varying delay in load frequency control (LFC) schemes. The effects of these delays must be considere...

Discrete-time Fractional-order Controllers

The theory of fractional calculus goes back to the beginning of the theory of di erential calculus but its inherent complexity postponed the application of the associated concepts. In the last decade the progress in the areas of chaos and fractals revealed subtle relationships with the fractional calculus leading to an increasing interest in the development of the new paradigm. In the area of a...

Solution to time fractional generalized KdV of order 2q+1 and system of space fractional PDEs

Abstract. In this work, it has been shown that the combined use of exponential operators and integral transforms provides a powerful tool to solve time fractional generalized KdV of order 2q+1 and certain fractional PDEs. It is shown that exponential operators are an effective method for solving certain fractional linear equations with non-constant coefficients. It may be concluded that the com...
