distributed model predictive control (DMPC) methods that are based on iterative optimization algorithms normally require a large number of communications between the controllers, especially when the number of subsystems is large. This can easily result in overloading the network which is normally shared between many different users. Therefore methods to reduce the load on the network while still satisfying convergence, feasibility, stability, and a certain level of performance are of a great importance. In this paper a novel event-based optimization algorithm is provided to reduce the number of communications in DMPC methods that are based on dual decomposition.

In this paper, a distributed model predictive control (DMPC) is proposed for the emergency voltage control of large-scale power systems. The main concept of DMPC is that the online rolling optimization of the full system is simplified into a small-scale optimization of multiple sub-areas. It can effectively eliminate or alleviate the dimension disaster, and can reduce the amount of computation. According to the features of DMPC, two kinds of improved DMPC algorithms, namely the communication based distributed model predictive control (C-DMPC-1) and the cooperative distributed model predictive control (C-DMPC-2), are proposed. First, the decomposition principle of DMPC is explained. Then, the rolling optimization model of these two C-DMPC algorithms are built respectively. A case study on New England system is used to validate the proposed algorithms. The results show that the algorithms can effectively enhance the system voltage stability.

Vehicle platoon control based on vehicle-to-vehicle (V2V) communication is one of the promising technologies to improve the performance of transportation systems. It has the potential to increase traffic throughput, improve road traffic safety and reduce energy consumption. This paper proposes an innovative distributed model predictive control (DMPC) solution to the cooperative adaptive cruise problem of heterogeneous vehicle platoons. The vehicles (or nodes) in a platoon are dynamically decoupled but constrained by spatial geometry. Each node solves a local open-loop optimal control problem in a distributed manner. The cost function is designed by considering the error between the predicted trajectory and the assumed trajectory, and the optimization is carried out by comprehensively considering platoon stability, passenger comfort, fuel economy and other objectives. The effectiveness of the proposed DMPC algorithm is verified by simulation in MATLAB, and is compared with the traditional linear PID controller under different working conditions.

A distributed model predictive control scheme that allows for the communication links between subsystems being either fully connected or partially connected, or totally disconnected is presented in this paper. By incorporating the inner product of manifest variables into the supply rate, an extended input-to-power-and-state stabilisability (IpSS) condition is firstly derived for nonlinear interconnected systems. Dynamic stabilising constraints are subsequently developed for subsystem predictive controllers based on a virtual perturbed-state-feedback strategy that accepts changes in the communication network. The stabilising constraint is rendered by a dissipation-based constraint with respect to manifest variables for nonlinear input-affine systems.

The hierarchical control structure, namely, primary, secondary and tertiary control, becomes the standard operation of islanded microgrid. However, due to the proliferation of renewable energy sources which fluctuate fast, the time scale separation of the secondary and tertiary control can make the operation of microgrid becomes less economic efficient. Therefore, we incorporate the economic dispatch (ED) into the secondary control level and a distributed model predictive control methodology is proposed to solve the optimization problem. The control framework is fully distributed and each distributed generation is able to communicate with other nodes for iterative calculation. To verify the novelty of the economic secondary control strategy, a microgrid with micro gas turbine, diesel generator, battery and renewable energy is simulated. A comparison with the centralized control strategy and distributed frequency/ED separating control strategy is presented as well.

This paper proposes a distributed model predictive control (DMPC) method for a half-vehicle system with active suspensions. First, the half-vehicle system is divided into three subsystems to reduce the system dimension. Considering the distribution characteristics of suspension control systems, a DMPC controller is designed for each suspension subsystem in order to inhibit the vehicle vertical and pitch motion. To evaluate the proposed control system, controllers with low cost micro-control units (MCU) are implemented, where a fast MPC method for real-time optimization based on continuation/general minimum residual (C/GMRES) method is realized and in-vehicle network FlexRay is used to exchange control information among these controllers. Finally, the implementation of DMPC controllers in MCUs is finished and the results show that vehicle comfortability can be improved by the proposed controllers.

This is a position paper on the current state of the art in distributed model predictive control (M PC) and our view on its future potential. We present results from a recent survey of 35 distributed MPC approaches. For this, we propose a way in which distributed MPC approaches can be categorized for comparison. We also link the potential that these approaches have to the domain of other fields such as integrated environmental optimal decision making and cyber-physical systems. Many challenges for realizing these links have to be faced. We present our views on how the advances in several highly active research domains could be used to overcome these challenges. As such, this paper is intended as a starting point for the exploration of various novel research cooperations.

distributed model predictive control for a hybrid system that comprises wind and photovoltaic generation subsystems, a battery bank and an ac load is developed in this paper. Consider that the wind subsystem and the solar subsystem are two spatial distributed energy generation systems, so we design a distributed MPC for optimal management and operation of distributed wind and solar energy generation system. The wind and solar generation system is characterized by nonlinearity. Therefore, neural model is used to approximating the dynamics of nonlinear process. Reasonable solution to the optimization and constraints by using distributed model predictive control is presented. The performance of the distributed model predictive control is show through computer simulation to illustrate the advantages of the proposed method.
