“…sec. Because of the fundamental characteristic of the sliding mode controller to eliminate disturbance of the system in finite time [23], we can see only a minute difference of the order of some microseconds in table 3, 4 for different SMC protocol. The relative LOS angle error is zero which shows that the missiles attain the desired relative LOS angle and precisely hit the target.…”

This paper presents a distributed time and space cooperative guidance law based on a higher-order sliding mode protocol for the consensus among multiple missiles in the Line of Sight (LOS) and perpendicular to the LOS direction using a Multi-Agent System (MAS) approach. A graph theory is used to represent the communication between the missiles and a leader-follower approach of MAS is used to design the super-twisting sliding mode protocol for the consensus. The cooperative guidance law not only ensures robustness but also reduces the convergence time and the chattering during the consensus among multiple missiles. The stability condition of the consensus is also derived using the Lyapunov function.The protocol is validated among 4 missiles in the given pattern with two scenarios (1) Missile launching with different velocities and (2) Missile launching with the same velocities. The simulation results show that the consensus is achieved in a finite time. Further to show the efficacy of the robust cooperative guidance law, the results are compared with the guidance law designed using classical sliding mode control protocol with constant-rate and constant propositional rate reaching law. From the comparative analysis, it is inferred that the distributed time and space cooperative guidance law based on a higher-order sliding mode protocol performs better in terms of time required for consensus, time to hit the target, and precision.

“…These unwanted phenomena can be unveiled through different modes of faults in the control system. In MGs, inverters are considered as real actuators [40]. Therefore, any failure or fault in these actuators might cause faulty signals in the control loop, which can affect the whole performance and stability.…”

This paper presents a distributed fault-tolerant finite-time control scheme for the secondary voltage and frequency restoration of islanded inverter-based Alternating Current (AC) Microgrids (MGs) considering input saturation and faults. Most existing distributed methods commonly design the secondary control layer based on ideal conditions of the control input channels of the MG without any faults and disturbances. At the same time, MGs are exposed to actuator faults that can significantly impact the control of MGs, and lead the MG in unstable situations. One of the other typical practical constraints in multi-agent systems such as MGs is saturation. The other novel idea is that a consensus-based scheme synchronizes the islanded MG's voltage and frequency to their nominal values for all DGs within finite time, irrespective of saturation and multiple faults, including partial loss of effectiveness and stuck faults simultaneously. Finally, the performance of the proposed control schemes are verified by performing an offline digital timedomain simulation on a test MG system through a couple of scenarios in MATLAB/Simulink environment. The effectiveness and accuracy of the proposed control schemes for islanded AC MGs are compared to previous studies, illustrating the privilege of that.
