Features: This book adopts a combination of theoretical research and practical application, focusing on introducing the theory of hierarchical fuzzy generalized model controllers, detailing the application of fuzzy controllers, and presenting typical complex control systems—fuzzy combustion control, with specific applications being boiler control and gasoline engine control. The book introduces hierarchical fuzzy control systems and adaptive gain scheduling control systems; adaptive fuzzy PID control, which presents simple and practical adaptive methods based on PID control laws; establishes an adaptive hierarchical fuzzy controller for objects with dynamic characteristics that vary with operating conditions, achieving closed-loop fuzzy gain scheduling and introducing stable supervisory control to ensure engineering stability of the control system. For large time-delay nonlinear processes with dynamic characteristics varying with known variables, a composite fuzzy controller based on Smith prediction and model reference adaptive control is established. Unlike time-delay nonlinear system robust controllers that focus on theory, this controller exhibits excellent engineering applicability and ease of implementation. The control system constructed not only has good dynamic response characteristics but also theoretically proven stability and convergence. The book introduces the principles and characteristics of the first domestically developed fuzzy inference chip with intellectual property rights, F200; details the development process and principles of the first general-purpose fuzzy regulator in China, GFC-2000B; the intelligent fuzzy combustion control system for boilers, establishing a non-analytical control system based on "controlled equipment description logic," and providing a detailed introduction to the hierarchical control system of boilers. The book elaborates on the complete control strategy of the engine, including warm-up control, open-loop and closed-loop air-fuel ratio control, dynamic compensation control, self-learning and adaptive control, highlighting the application of fuzzy control in engine electronic control systems. The book introduces the basic principles of ignition control, particularly describing the knock identification algorithm used for closed-loop ignition control. Fault diagnosis and fault-tolerant probability control of combustion controllers are also introduced. The book covers the full range of engine fault diagnosis and non-analytical reconstruction fault-tolerant control. This book is primarily intended for science and technology personnel engaged in process control (e.g., boiler control) and automotive control, as well as for students and teachers at universities and colleges in related fields.
