Nonconservative stability conditions of discrete-time systems with constrained delays

Key Points

• Instabilities were identified in discrete-time systems under nonconservative conditions, leading to unexpected dynamic behavior.
• The findings demonstrate that systems with constrained delays exhibit significant vulnerabilities, particularly under feedback control scenarios.
• Observational analysis of multiple systems was conducted to assess their stability due to delays, indicating a need for improved theoretical understanding.
• The implications suggest a re-evaluation of existing stability frameworks for discrete-time systems to enhance performance in control applications.
