this paper presents the treatment of artificial discontinuities in a Hamiltonian-based optimal control of holonomically-constrained multibody systems. Discontinuities considered here are defined as artificial. As opposed to, e.g., impacts or unilateral constraints, they do not originate from physical phenomena, but they are the result of a particular action took against possible numerical issues instead. this action transforms the system into a hybrid one in which discrete events have to be considered. In the proposed approach, a general optimal control problem is formulated by approximating the optimal solutions with Chebyshev polynomials of the first kind in order to bound the number of design variables. the optimal control problem is solved by employing an efficient adjoint-based technique. A derivation of jump conditions for both state and adjoint variables are shown. An example showcasing the implementation of the proposed method is included as well. this work presents an intermediate step in deriving a framework, which would directly operate on time functions instead of time-independent parameters.

Dielectric Elastomer Actuator (DEA) based soft robots are gaining widespread recognition for numerous applications such as;medical devices, bio-inspired systems and flexible prosthetics to name but a few. Due to their nonlinearity relating mostly to hysteresis and creep, most DEAs are subject to precision positioning *** enable precise positioning, control-enabling DEA models and controllers are developed to curb the issues of their nonlinear dynamics. this paper presents a new Sliding-Mode Control (SMC) based on reaching law for precise position tracking of an adopted simplified and experimentally validated DEA model. the proposed reaching law incorporates a high-slope saturation function with an exponential denominator to drastically reduce chattering and enhance fast and finite convergence. the sliding-mode controller stability is validated using a Lyapunov candidate for asymptotic stable. Finally, Closed-loop simulations demonstrating the controller's effectiveness at suppressing chattering and tracking wide-band trajectories (triangular and sinusoidal) were implemented.

In this paper the lossless block encoder application using the adaptive Golomb code and asymmetric inter-channel dependencies are presented. Using the sets of settings obtained from the study of inter-channel dependencies, the lowest bit averages were found within the channels. In the next step the algorithm was improved by adaptation within the blocks, what allowed to improving the degree of compression.

this paper presents a recursive and parallel formulation for the dynamics simulation of large articulated robotic systems based on the Hamilton's canonical equations. Although Hamilton's canonical equations exhibit many advantageous features compared to their acceleration based counterparts, it appears that there is a lack of dedicated parallel algorithms for multi-rigid body dynamics simulation based on such formulation. In this paper we consider open-loop kinematic chains that are connected by kinematic joints. Initially, the standard set of Hamilton's canonical equations are joined together with the constraint equations at the velocity level. the formulation allows to determine the system's joint velocities and impulsive constraint forces in a divide and conquer framework. this operation results in logarithmic numerical cost in parallel implementation. Subsequently, the time derivatives of the total joint momenta are evaluated at the constant expense. In case of sequential implementation, the entire algorithm exhibits linear computational cost. the proposed method is exact, non-iterative and does not require the direct calculation of the system's Hamiltonian nor its partial derivatives. Numerical test cases reveal negligible energy drift without the use of any additional constraint stabilization techniques. the results are compared against more standard acceleration based formulation and the preliminary outcome from real-life physical experiment.

Stress is an increasingly common problem. thanks to the use of various mathematical methods, it can be described mathematically based on the EEG signal. Generally, the stress in mathematical analysis can be divided into several models. To determine the variability in the stress-related EEG signal, the periodograms used for the overall assessment are checked.

A general tracking problem is formulated and solved for a third-order Duffing-Holmes type chaotic oscillator implemented as an electronic circuit with unknown parameters. Two nonlinear controllers, based on adaptive backstepping techniques, are derived and compared. Both are sufficiently robust and accurate for practical implementation. the same approach may be used for chaos stabilization and synchronization.

作者： Witold Byrski Michał Drapała Department of Automatic Control and Robotics AGH University of Science and Technology Kraków

Adaptive identification method based on modulating function approach is described in this paper. the real glass melting process is modelled by a linear system, which parameters values can be changed on-line during the identification procedure. the overall model is composed of several submodels. the models, which inputs can be controlled, are approximated by the Strejc transfer function. this approach allows to reduce the number of model parameters. Moreover, PID tuning methods dedicated to the Strejc models can be applied. the developed procedure was applied for data collected from a real glass containers production installation.

the stability problem of fractional discrete-time linear systems with delays has been analysed. the state-space model with a time shift in the difference has been considered. New necessary and sufficient conditions for the asymptotic stability and the practical stability have been established. the systems with only one matrix have been also analysed. It has been shown that such systems are asymptotically (practically) stable if all eigenvalues of the state matrix lie in the stability region of the complex plane.

Stabilization of a linear discrete-time large-scale interconnected systems composed of identical subsystems is studied. the controls of every subsystem are delayed. the control design is based on a state transformation that decouples the subsystems. then, a suitable design method is used. Robustness to deal with systems with uncertainties is guaranteed. the results are illustrated by an example.

作者： Przemyslaw Herman Wojciech Adamski Institute of Automation and Robotics Poznan University of Technology Poznan Poland

this paper deals with the problem of trajectory tracking control for some vehicles (underwater vehicles, and indoor airships). the approach uses a velocity transformation which results from the inertia matrix decomposition. Next, a model-based non-adaptive nonlinear tracking controller in terms of the Generalized Velocity Components (GVC) is proposed. An important property of the algorithm is that the control gains are closely related to the dynamics of the vehicle (especially dynamical couplings). the general algorithm was given for a 6 DOF vehicle and tested using simulation. the results obtained for a full airship model have shown that the control scheme guarantees satisfactory performance.
