The indoor rowing exercise is introduced as a total body exercise for rehabilitation of function of lower extremities of paraplegics through the application of functional electrical stimulation (FES). Fuzzy logic control (FIX) is implemented to control the knee and elbow trajectory for the purpose of smooth rowing manoeuvre. Conventional FIX methods rely on simple experiences and trial and error for parameters identification. In this work, the FIX is optimized using genetic algorithms (GAs), a stochastic global search method. GA implementation incorporates dynamic crossover and mutation probabilistic rates for faster convergence. The objective function of GA is to maintain smooth rowing manoeuvre. The performance of the proposed GA-tuned FLC is compared to a conventional manually tuned FLC. It is demonstrated that the developed controller offers encouragingly better performance.
In this paper, we present a feedback-based framework for controlling the evolution of quantum spin states of nuclei within an ensemble. This approach allows for the selective excitation of nuclear spin states within s...

This paper presents mathematical modelling of a single-link flexible manipulator in vertical plane motion. This extends the previously developed mathematical model for motion in the horizontal plane, where the effects of gravity, rotary inertia and shear deformation were ignored. The dynamic model of the system is obtained using the Lagrange equation. The finite difference method is used to transform this into a discrete formulation. The dynamic behaviour of the system in vertical motion is studied using the developed algorithm. Simulation results of the response of the manipulator are assessed in comparison to corresponding theoretical ones in the time and the frequency domains to verify the accuracy of the algorithm in characterizing the behaviour of the flexible manipulator system.
