Abstract Stability and bifurcation analysis of a non-rigid robotic arm controlled with time-delayed acceleration feedback loop is addressed in this work. The study aims at revealing the dynamical mechanisms leading to appearance limit cycle oscillations existing stable region trivial solution system, which related combined dynamics robot control its structural nonlinearities. An analytical bifu...

2-D laminar flow with natural Convection with different checker board removing approaches (staggered and collocated grid systems) is solved to provide comparison between staggered and collocated arrangements. SIMPLEC algorithm is employed for pressure velocity coupling. The results are first presented for a benchmark problem and then the effect of the inclination angle and aspect ratio are inve...

In this paper, we introduce homogeneous cosimulation method, which is suitable for modeling and simulation of systems comprising hardware (HW) and software (SW) components. In this method, a hardware description language with embedded programming capabilities (like VHDL) is used to model both HW/SW parts at any desired level of abstraction. Because of platform homogeneity, no sophisticated coor...

This work addresses a versatile modeling of complex photonic integrated circuits (PICs). We introduce a cosimulation solution for combining the efficient modeling capabilities of a circuit-level simulator, based on analytical models of PIC sub-elements and frequency-dependent scattering matrix (S-matrix) description, and an accurate electromagnetic field simulator that implements the finite ele...

In this paper, a method of calculating the parameters of equivalent circuit model of linear induction motor(LIM) is proposed based on numerical analysis and finite element method(FEM). The method is proved accurately through the traditional removed and locked tests. Material change of reaction plate’s effect on how equivalent circuit’s parameters change and the influence on thrust and vertical ...
