In this paper, we analyse the instability of a thin-film suspension micro-swimmers subjected to an attractant gradient. The imposed gradient introduces preferential swimming direction for swimmers, resulting in anisotropic orientation field. By modelling swimmers as force dipoles, study by Kasyap & Koch ( Phys. Rev. Lett. , vol. 108, issue 3, 2012, 038101, J. Fluid Mech. 741, 2014, pp. 619–...

In this paper, an iterative technique is proposed to solve linear integrated active/passive design problems. The optimality of active and passive parts leads to the nonlinear algebraic Riccati equation due to the active parameters and some associated additional Lyapunov equations due to the passive parameters. Rather than the solution of the nonlinear algebraic Riccati equation, it is proposed ...

Suspension system plays an imperative role in retaining the continuous road wheel contact for better road holding. In this paper, fuzzy self-tuning of PID controller is designed to control of active suspension system for quarter car model. A fuzzy self-tuning is used to develop the optimal control gain for PID controller (proportional, integral, and derivative gains) to minimize suspension work...
