Nonlinear Control Systems

Definition

Expert knowledge refers to the specialized understanding and skills that individuals acquire through extensive experience and education in a particular field. This type of knowledge is often essential in making informed decisions, particularly in complex systems where intuition may not suffice. In control systems, expert knowledge is crucial for formulating rules and heuristics that guide decision-making processes, especially when dealing with uncertain or imprecise information.
