In a context of heightened requirements for safety-critical embedded systems and
ever-increasing costs of verification and validation, this research proposes to
advance the state of formal analysis for control software. Formal methods are a
field of computer science that uses mathematical techniques and formalisms to
rigorously analyze the behavior of programs. This research develops a framework
and tools to express and prove high level properties of control law
implementations. One goal is to bridge the gap between control theory and
computer science. An annotation language is extended with symbols and axioms to
describe control-related concepts at the code level. Libraries of theorems,
along with their proofs, are developed to enable an interactive proof assistant
to verify control-related properties. Through integration in a prototype tool,
the process of verification is made automatic, and applied to several example systems.In a context of heightened requirements for safety-critical embedded systems and
