this paper studies the problem of computing feed-forward control input signals for a solenoid actuator based on a distributed parameter model. the solution is expressed as a power series, and a backward/forward procedure is suggested to verify the approach and to investigate the effect of simplifications. Experimental results from a lab test rig are provided to show that this approach can provide feed-forward control signals which are able to steer the system along the desired trajectory.

the present paper described the implementation of an adaptive scheme of the direct field oriented control (DRFOC) for an induction motor. A nonlinear estimator is suggested to estimate the rotor time constant inverse and thereafter it will be used with motor model to estimate the rotor flux. Both rotor flux and parameter estimations are hardware performed by using the Xilinx System Generator (XSG) for DSP within the Matlab/Simulink environment.

We propose a novel approach for transferring evolved control systems from a simulated environment to a real robot. Multiple dynamic simulation systems are simultaneously employed to provide a valid range of simulation variance that can be exploited to generate robust controllers in a purely virtual environment. these controllers can then be directly transferred to a physical robot.

In this paper, a consistent kinematic modeling method for mobile manipulators is proposed. We transform the mobile manipulators into conventional manipulators via appropriate change of kinematic structure. Consequently, analyses of kinematics for mobile manipulators can be conveniently carried out withthe transformed manipulators. Cases of differential-drive and car-like types of mobile platforms are formulated, but theoretically not limited to these.

In this contribution a concept is presented, which offers independent controllability of pressure and flow-rate whitin process plants. the dynamic of those plants is highly nonlinear and the control variables are coupled. Furthermore, time delays have to be considered. the proposed control concept consists of a nonlinear decoupling controller in combination with an extended smith predictor. the functionallity of the controller is demonstrated by measurements on a test bench.

In this paper various methods of ergonomics improvement in electric bicycle pedaling are discussed. the main goal is to control an average amperage of generator powered by a cyclist, but considering the unsteadiness of human legs torque vs. angular position of the support. In the paper, four different approaches for generating the current reference trajectory are compared - two of them use only position signal, and the next two use also velocity signal in the ergonomic improvements calculations.

In this paper, a sliding mode control scheme is developed for a class of complex nonlinear systems withtheir T-S fuzzy models. It is shown that a set of extreme fuzzy subsystems are first derived, and a constructive sliding mode control law is then developed to guarantee the stability of the closed-loop fuzzy system. Simulation results are presented in support of the proposed scheme.
