The Dielectrophoretic (DEP) force arises as a result of the interaction between a nonuniform electric field and a neutrally charged particle. As the effect of the electric field is more dominant than other forces at the micro/nano scale, this force can be effectively used to manipulate and control particles on this scale. We consider the motion of a particle on an invariant line with the suspending medium being a fluid with low Reynolds number. The system is described by a set of ordinary differential equations with a quadratic term in the control variable (control being the applied voltage on the electrodes which induces the electric field) making the system non-affine. For this system, we address certain aspects of existence and uniqueness of the time-optimal trajectories.

In this paper, we present a Bernstein polynomial approach to optimally and reliably solve polynomial class of mixed-integer programming (MIP) problems. We use the Bernstein form in the branch-and-bound framework to compute a global optimum of MIPs. We present two application examples of MIPs: optimal pump configuration problem and trim loss minimization, to demonstrate the Bernstein polynomial approach.

This paper presents a new formulation for “Equivalent control” used in sliding mode control. Although in literature there exist a unique equivalent control for a given system and linear sliding surface, it is shown that the equivalent control can be non unique. Further this flexibility in equivalent control is used to obtain the sliding mode control for specific needs such as actuator saturation, faster reaching without increasing chattering, confining the sliding mode in a specified sector and simple second order sliding mode control design.

This paper proposes a discretization behavior of nonlinear sliding surface based algorithms. Recently nonlinear surfaces are proposed by the authors to improve transient performance of continuous and discrete-time uncertain systems. The nonlinear surface changes system's closed loop damping ratio as output approaches the setpoint. In this paper we propose a nonlinear surface for the system represented by delta operator approach which unifies our continuous-time and discrete-time results.

Dielectrophoretic (DEP) force is a result of the interaction between a nonuniform electric field and a particle. As the electric field is dominant at the micro/nano scale, this force can be effectively used to manipulate and control particles on this scale. We consider the motion of a particle on an invariant line with the suspending medium being a fluid with low Reynolds number. This DEP system has two states and two parameters: the two states are indicative of the particle position and the induced dipole moment, the two parameters are a and c which depend upon the electric properties of the particle and the medium. The system is described by a set of ordinary differential equations with a quadratic term in the control variable (control being the applied voltage on the electrodes which induces the electric field) making the system non-affine. For this system, we address the issues of reachability, accessibility and controllability.

With the addition of online laboratories, distance education can become more meaningful and complete. This paper presents a virtual lab established through LabVIEW data socket technology that enables the end user to design and implement control algorithms. Although this makes the problem more challenging, the quality of learning is also enhanced enormously. We demonstrate this lab through an open source, low cost, single board heater system. A large number experiments have been conducted using this setup.
