Analysis of Applying Event-triggered Strategy on the Model Predictive Control
نویسندگان
چکیده مقاله:
In this paper, the event-triggered strategy in the case of finite-horizon model predictive control (MPC) is studied and its advantages over the input to state stability (ISS) Lyapunov based triggering rule is discussed. In the MPC triggering rule, all the state trajectories in the receding horizon are considered to obtain the triggering rule. Clearly, the finite horizon MPC is sub-optimal with respect to the infinite-horizon case. This sub-optimality is considered as a coefficient to implement the MPC triggering rule and to increase the inter-execution time. However, to design a proper processing board to control this coefficient suitably, it is necessary to specify lower and upper bounds for it. The contribution of this paper is to determine an effective upper bound for this coefficient. By incorporating the sub-optimal lower bound instead of being 1, the conservatism decreases. This coefficient can be used as a tunable parameter in integrated or network control systems to compromise between the performance and inter-execution time. Simulation results depict the applicability of the proposed method and validate the theoretical results.

Event-triggered intermittent sampling for nonlinear model predictive control
In this paper, we propose a new aperiodic formulation of model predictive control for nonlinear continuous-time systems. Unlike earlier approaches, we provide event-triggered conditions without using the optimal cost as a Lyapunov function candidate. Instead, we evaluate the time interval when the optimal state trajectory enters a local set around the origin. The obtained event-triggered strate...
متن کاملLyapunov event-triggered control: a new event strategy based on the control
Event-triggered control is a sampling strategy that updates the control value only when some events occur. An event is usually generated by an event-function that indicates if the control signal must be updated or not. If one excepts self-triggered implementation, event-triggered control requires the evaluation of the event function at each time instant. Unfortunately, in the literature of nonl...
