“…This approach was generalized to nonlinear systems in Walsh et al [245]. The practical implementation of the MEF-TOD algorithm was considered in [243]. This implementation, which was performed on CAN networks, is mainly based on the nondestructive bitwise arbitration of CAN technology to dynamically encode the dynamic priorities.…”

“…In the NCS discussed in this paper, controller and actuator are event-driven, whereas sensor is clock-driven. Therefore, the forward and feedback channel time-delay of NCS can be combined [11,14] , the system total delay can be expressed as…”

Abstract:A network time-delay compensation method based on time-delay prediction and implicit proportional-integral-based generalized predictive controller (PIGPC) is proposed. The least squares support vector machine (LSSVM) is used to predict the current time-delay, the parameters of the least squares support vector machine are optimized by particle swarm optimization (PSO) algorithm, and the predicted time-delay is used instead of the actual time-delay as the parameters of the network time-delay compensation controller. In order to improve the compensation effect of implicit generalized predictive controller (GPC), this paper puts forward an implicit generalized predictive control algorithm with proportional-integral-based (PI) structure and designs the controller based on implicit PIGPC. Through the simulation results, the effectiveness of this design in the paper is verified.

“…In a series of recent papers [Walsh et al, 1999[Walsh et al, , 2002[Walsh et al, , 2002b, [Walsh & Ye, 2001], the try-once-discard (TOD) protocol is proposed and studied intensively, where an upper bound of sensor-to-controller time delays induced by the network is derived, for which exponential stability of the closed-loop system is guaranteed.…”

A new network data transmission strategy was proposed in Zhang & Chen [2005] (arXiv:1405.2404), where the resulting nonlinear system was analyzed and the effectiveness of the transmission strategy was demonstrated via simulations. In this paper, we further generalize the results of in the following ways: 1) Construct first-return maps of the nonlinear systems formulated in Zhang & Chen [2005] and derive several existence conditions of periodic orbits and study their properties. 2) Formulate the new system as a hybrid system, which will ease the succeeding analysis. 3) Prove that this type of hybrid systems is not structurally stable based on phase transition which can be applied to higher-dimensional cases effortlessly. 4) Simulate a higher-dimensional model with emphasis on their rich dynamics. 5) Study a class of continuous-time hybrid systems as the counterparts of the discrete-time systems discussed above. 6) Propose new controller design methods based on this network data transmission strategy to improve the performance of each individual system and the whole network. We hope that this research and the problems posed here will rouse interests of researchers in such fields as control, dynamical systems and numerical analysis.
