- 요약The Newton-Raphson Controller is a tracking controller built on the ideas of output prediction and the Newton-Raphson method. Existing results have already shown that the controller is capable of controlling a variety of nonlinear systems, including the inverted pendulums, autonomous vehicles and quadrotors. Compared to other tracking control approaches, the Newton-Raphson Controller features similar or better tracking accuracies while requiring less computational resources.Despite its early success, several problems still remain in the current version of the Newton-Raphson Controller. To begin with, this controller is model-based, meaning that it requires a mathematical model of the controlled plant in order to calculate a proper control input. Moreover, although there has already been a verifiable stability criterion of the Newton-Raphson Controller for linear systems, such criterion for nonlinear systems is yet to be proposed. Lastly, this controller can only be applied to single-agent systems. To apply the Newton-Raphson Controller in a multi-agent system, we must explicitly design the reference signal for each agent and convert the multi-agent control problem into multiple single-agent control problems.The problems mentioned above have prevented the use of the Newton-Raphson Controller in many control applications. Therefore, in this dissertation, we attempt to solve these problems and improve the existing controller, such that it can be applied to more control scenarios. Specifically, we study the following aspects of the Newton-Raphson Controller: First, we attempt to make the Newton-Raphson Controller model-free using the Deep Neural Network (DNN), such that the controller does not rely on the mathematical models of the controlled plants. Second, we perform stability analysis and propose verifiable stability criteria of the controller for a class of differentially flat systems. Third, we try to extend the current single-agent controller to a multi-agent controller, such that it can achieve leaderless consensus over a class of heterogeneous multi-agent systems.Fourth, we develop the leaderless consensus controller into the leader-follower consensus controller, which allows the controlled agents to follow a leader or a reference signal while maintaining consensus. Finally, to avoid inter-agent collisions during the consensus control, we propose to apply the Integral-Control Barrier Function to maintain a proper distance between agents and keep the agents safe. We will demonstrate the effectiveness of the improved controller using a number of simulations on different nonlinear systems and show that the proposed methods are capable of solving a variety of control problems. The simulation results together with the theoretical developments suggest a potential of the improved controller in future applications.
