Online Adaptation of Data‐Driven Controllers for Unknown Nonlinear Systems
ABSTRACT This paper considers data‐driven online control of input‐affine nonlinear systems. By resorting to a data‐based closed‐loop time‐varying system representation, we derive data‐based online semi‐definite programs that are computed along the system's trajectory.

This paper presents a robust H∞ decentralised and centralised control approach for a microsurgical manipulator using Particle Swarm Optimisation and Gravitational Search Algorithm (PSOGSA). The proposed fixed‐structure Proportional‐Integral‐Derivative (PID)‐based controllers address implementation challenges of conventional high‐order H∞ controllers ...

Dynamical Modelling and Optimal Control of Conjunctivitis Epidemic
Conjunctivitis disease was modelled using a deterministic modelling approach, with the dynamics presented by the compartments in the flowchart. The results showed that intervention D is the best cost‐effectiveness policy. ABSTRACT In this study, we develop a mathematical model for conjunctivitis transmission dynamics.

ABSTRACT Microgrids with integrated renewable energy sources are becoming more and more important in the fast‐changing electrical energy production scenario. An 8 kW wind generator and a 4.5 kW solar photovoltaic system are the two renewable energy sources utilized in the hybrid alternating current (AC) and/or direct current (DC) microgrid ...

Sequence-based Anytime Control
We present two related anytime algorithms for control of nonlinear systems when the processing resources available are time-varying. The basic idea is to calculate tentative control input sequences for as many time steps into the future as allowed by the

Parametric Study on the Performance of Gas Springs in FPSE With Pneumatic Supporting System
ABSTRACT The introduction of a pneumatic supporting system composed of gas springs and hydrostatic bearings in the free‐piston Stirling generator (FPSG) can effectively increase the power density of the nuclear space power plant. In this paper, a 1 kW FPSG with pneumatic supporting system was developed, and the working characteristics of dual gas ...

Error‐Based Virtual Compound Axis With Backstepping Control for Electro‐Optical Tracking System
In this paper, an error‐based virtual composite‐axis disturbance rejection backstepping control strategy is proposed for the electro‐optical tracking system that cannot improve the tracking accuracy by the composite‐axis structure because the target position, velocity, and acceleration are unknown and cannot be measured directly.
