Real-Time System Verification by k-Induction

Control Simulation and Experimental Verification of Maximum Power Point Tracking Based on RT-LAB (TECHNICAL NOTE)

The maximum power point tracking (MPPT) control in the Photovoltaic system is the key control technology, however present controller has the disadvantages of long development cycle, high cost and complex verification, and there are some disadvantages carrying out totally physical simulation or totally digital simulation of different control algorithms. This paper carried out design of hardware ...

Timeout and Calendar Based Finite State Modeling and Verification of Real-Time Systems

We revisit the problem of real-time verification with dense time dynamics using timeout and calendar based models, originally proposed by Dutertre and Sorea, and simplify this to a finite state verification problem. To overcome the complexity of verification of real-time systems with dense time dynamics, Dutertre and Sorea, proposed timeout and calender based transition systems to model the beh...

Safety Verification of Real Time Systems Serving Periodic Devices

In real-time systems response to a request from a controlled object must be correct and timely. Any late response to a request from such a device might lead to a catastrophy. The possibility of a task overrun, i.e., missing the deadline for completing a requested task, must be checked and removed during the design of such systems. Safe design of real-time systems running periodic tasks under th...

Modeling and Verification of a Fault-Tolerant Real-Time Startup Protocol Using Calendar Automata

We discuss the modeling and verification of real-time systems using the SAL model checker. A new modeling framework based on event calendars enables dense timed systems to be described without relying on continuously varying clocks. We present verification techniques that rely on induction and abstraction, and show how these techniques are efficiently supported by the SAL symbolic model-checkin...
