**Preface to "Advances in Condition Monitoring, Optimization and Control for Complex Industrial Processes"**

Complex industrial automation systems/processes place high demands on system operation performance and reliability. Recent advances in monitoring, optimization, and control techniques have enabled an improved understanding of systems dynamics and an enhanced achievement of reliable monitoring and control in complex industrial processes. This Special Issue, composed of state-of-the-art review paper and intensive research papers, has highlighted advances in this field. This collection demonstrates the versatility of the area, ranging from theoretical algorithms to experimental implementation of complex industrial processes.
