A control strategy for changing the position of an immersed micro particle in a viscous medium and trapped by optical tweezers is presented. The feedback controller was designed under the consideration that the mass of the micro particle is sufficiently enough so it can be discarded from the equations of motion. In practice it is true, since the inertial force produced by the motion of a micron-scaled...
We present an energy matching control strategy model for the angular velocity stabilization of a rigid body system that assumes that two independent controllers are available. The control strategy consists of solving a feasible matching condition in order to derive a feedback controller which forces the closed-loop system to be globally asymptotically stable.
The stabilization of the strongly damping inertia wheel pendulum around its unstable equilibrium point is presented in this paper. The fact that this system can be rewritten approximately as a chain of integrators with and nonlinear perturbation suggests the use of a nested saturation based controller for making all state variables converge to zero. The proposed control strategy makes the closed-loop...
