In this module, we focus on the verification of finite systems, particularly emphasizing regular safety properties and ω-regular properties (including those expressed as linear temporal logic formulae). We will explore a variety of verification techniques and delve into the theoretical underpinnings essential for understanding how finite systems are verified. Through detailed examples and clear, comprehensive explanations, we aim to provide a deep understanding of how these properties are verified in the context of finite systems.

In this module, we explore the synthesis of controllers for finite systems, focusing on enforcing certain linear temporal logic (LTL) formulas, including safety, reachability, persistence, and recurrence. We aim to understand how controllers can be designed to render specific LTL formulas for closed-loop systems. The module provides essential theoretical frameworks and practical algorithms necessary for synthesizing such controllers, with an emphasis on the roles of fixed-point operators and algorithms in the computation processes. Additionally, we will discuss various synthesis techniques that depend on the properties of the system and the involved LTL formulas.

In this module, we will explore the concepts of abstraction and refinement within the context of control systems. We will delve into feedback refinement relations to understand how controllers can be modified or replaced to meet new specifications without altering the overall system behavior. The module also covers the computation of abstractions, demonstrating how we derive abstract models from complex systems to facilitate analysis and design. Additionally, we will discuss practical methods for abstracting different types of control systems, equipping us with the skills to apply theoretical concepts in real-world scenarios.
