This study is dedicated to the problem of non linear attitude control for a rigid large angle maneuver satellite. The non linear control method is based upon the linearization of the input-output of the system, also called feedback linearization, via state feedback. The output function is chosen amongst the attitude quaternion parameters.

With the application of distributed clocks synchronised with low jitter, devices interconnected with Ethernet switches can exchange data deterministically. To be applicable for motion control, low latency is required in addition to determinism. This paper presents a summary of network calculus and its application to real examples. Practical restrictions to the variables within the calculus are offered to show that devices utilising only standard Ethernet hardware and protocols can be used for high performance motion control.

The paper proposes a procedure for the iterative computation of a robot inverse kinematics that uses different algorithms in synergy, so to obtain a singularity-robust and rapidly convergent technique. The application of such a procedure allows the creation of a unified version of the executable code for large classes of industrial robots, with the possibility to introduce new kinematic chains or more complex structures without the need to entirely rewrite the code. The paper offers also some guidelines about the software implementation and optimization in the industrial environment, and it is completed by experimental results where the procedure is applied to real industrial robots.

In this paper two control algorithms for constrained synchronization control of networked Euler-Lagrange (EL) systems are developed. The first proposed distributed control law requires full state feedback where boundedness of the control efforts are guaranteed for all initial system conditions. The second proposed control law is based on output feedback and does not require velocity measurements. Simulation results for the state synchronization control of networked planar robots are reported to verify our theoretical analysis and to compare performance of our proposed synchronization controllers with other results that are available in the literature.

An integrated navigation, guidance and control system is designed for an uninhabited surface vehicle named Springer built at Plymouth University. Interval Kalman filtering is used for navigation. Line of sight is used for guidance. Model predictive control is utilised to build the control system, or autopilot. The performance of this innovative navigation, guidance and control system is benchmarked against a conventional optimal method based on a linear quadratic Gaussian controller which uses traditional Kalman filtering. The performance of the systems are compared and analysed in this paper.

With the advent of Electrically Pedal Assisted Cycles (EPACs), bicycles are becoming more and more technologically advanced, and active control systems are being developed to deal both with rideability enhancement and with energy management features. Within this context, this paper investigates the design of the control system for a continuously variable transmission, that allows a fine regulation of the transmission ratio and can thus improve the riding feeling with respect to a standard bicycle gear system. This control system is to be seen as the enabling step to design higherlevel control systems that will allow to optimize the rider's effort in an EPAC, by designing a gear shifting policy which achieves the best trade-off between energy consumption and rideability. Experimental results are presented which witness the effectiveness of the proposed approach.

This paper presents the new Robust Nonlinear Fuzzy control (RNFC) problem for uncertain nonlinear systems and also presents a Takagi-Sugeno (TS) fuzzy model-based maximum power control approach. First, the maximum-power-voltagebased control scheme and direct maximum power control scheme are introduced for the maximum power point tracking (MPPT). Furthermore, the MPPT robustness is also discussed to cope with varying atmosphere and system uncertainties. Second, the nonlinear system with parametric uncertainties is represented by the TS fuzzy model. Next, in order to reduce the number of measured signals, a TS fuzzy observer is established for state feedback. Then, the concept of Parallel Design Compensation (PDC) is employed to design RNFC from the TS fuzzy models. The sufficient conditions are formulated in the format of Linear Matrix Inequalities (LMIs) to obtain the observer and controller gains. The effectiveness of the proposed controller design methodology is finally demonstrated through a photovoltaic panel array to maximize the PV power.
