There are many practical systems which can be modelled by dynamical equations. Increasing requirements on system performance mean that within control system analysis and design it is necessary to deal with the increasingly complex dynamical systems that are used to model reality. The complexity stems from nonlinearity, uncertainty, time delay, system singularity, stochastic effects, the presence of interconnections, and so forth. Advances in both technology and control theory have provided the potential to investigate complex dynamical systems. Study on complex systems is becoming increasingly important and this has provided renewed impetus for the development of novel techniques and skills for complex control systems. This provides the motivation for this special issue.

The purpose of this special issue is to provide an opportunity for scientists and control engineers to publish their latest, novel, and original contributions to the development of complex control systems. The special issue focusses on recent achievements and applications in the field of control and analysis for complex systems with a special emphasis on how to solve various control design and/or observer design problems for nonlinear systems and interconnected systems. The considered systems typically involve at least two features such as nonlinearity, disturbances/uncertainty, faults, time delay, interconnections between subsystems, system singularity, stochastic processes, and comparison between simulation and experiments. The special issue focuses on results in theoretical research and practical applications with emphasis on novel methodologies for analysis, design, synthesis, and/or applications. The topics within the special issue include interconnected/networked systems, variable structure control, singular system control, time delay systems, fuzzy control and impulsive control, robust observer design and parameter identification, fault detection and fault tolerant control, analysis and control of stochastic systems, and applications of advanced control systems.

A total of 109 papers were submitted to the special issue for possible publication and 38 of them were accepted and published following a fair and rigorous review process organised by the guest editorial team with the help of the editorial office. The acceptance rate is less than 35%. The accepted papers have been grouped in the following six clusters.

(1) Interconnected/Networked Systems. There are 8 papers considering interconnected or networked systems. The important issue of controllability/observability for interconnected descriptor systems is discussed in “Impulsive Controllability/Observability for Interconnected Descriptor Systems with Two Subsystems” by Q. Zhang et al. Complex networked systems are discussed in the following papers: “Optimal Control of Probabilistic Logic Networks and Its Application to Real-Time Pricing of Electricity” by K. Kobayashi and K. Hiraishi, “Nonfragile Robust Synchronization Approach for Drive-Response Complex Dynamical Networks with Randomly Occurring Controller Gain Fluctuations and Uncertainties” by D. Li et al., and “Control of Synchronization and Stability for Nonlinear Complex Dynamical Networks with Different Dimensional Similar Nodes and Coupling Time-Varying Delay” by L. Yi-ping et al. Decentralised control schemes are proposed in “Decentralized Control for Large-Scale Systems with Uncertain Missing Measurements Probabilities” by Y.

(2) Time Delay System and Sliding Mode Control. Continuous time delay systems are considered in “The Application of Time-Delay Dependent Control Model in Manufacturing Decision Optimization” by H. Guo et al., and discrete time delay systems are discussed in “Efficient Approach to Stability Analysis of Discrete-Time Systems with Time-Varying Delay” by S. W. Yun and S. H. Kim and “Stabilization of Discrete-Time Delayed Systems via Partially Delay-Dependent Controllers” by G. Wang and B. Li.

An iterative learning control approach with extended observer is proposed to enhance the tracking precision of a telescope in “Iterative Learning Control with Extended State Observer for Telescope System” by H. Cai et al. Different filters are designed for various applications in “Initial Self-Alignment for Marine Rotary SINS Using Novel Adaptive Kalman Filter” by F. Pei et al. and “Model Free Command Filtered Backstepping Control for Marine Power Systems” by H. Zhou et al. Parameter identification is provided in “Channel Parameters Identification Based on IMM Algorithm for Variant Correlation Channel” by Z. Yang et al.

(6) Other Control and Practical Applications. In this special issue, other approaches such as fractional control, distributed control, backstepping, adaptive control, and model predictive control are also employed by some authors, for example,“Fractional Order Controller Designing with Firefly Algorithm and Parameter Optimization for Hydroturbine Governing System” by L. Junyi and Q. Chen, “Distributed Control Design for Structures Subjected to Traveling Loads” by D. Pisarski, “Adaptive Neural Back-Stepping Control with Constraints for a Flexible Air-Breathing Hypersonic Vehicle” by P. Wang et al., and “Design and Implementation of Recursive Model Predictive Control for Permanent Magnet Synchronous Motor Drives” X. Wu et al. Quite a few papers focus on the application of control methods in various practical systems, for example, “Robust Adaptive Attitude Control for Airbreathing Hypersonic Vehicle with Attitude Constraints and Propulsive Disturbance” by J. Fu et al., “Global Chassis Control System Using Suspension, Steering, and Braking Subsystems” by C. A. Vivas-Lopez et al., “Control Strategy of Three-Phase Photovoltaic Inverter under Low-Voltage Ride-Through Condition” by X.
