QUEST: A Tool for State-Space Quantization-Free Synthesis of Symbolic Controllers (C++ toolbox)

Last updated on Mar 7, 2020

QUEST is an open source software tool, developed in C++, for automated controller synthesis for incrementally input-to-state stable nonlinear control systems. The tool contains two major parts:

  1. Construction of symbolic abstraction: the tool uses state-space quantization-free approach for the construction of symbolic abstraction which can be potentially more beneficial for systems with high-dimensional state spaces.
  2. Symbolic controller synthesis: the synthesis of controller using fixed point computations, namely, maximal and maximal fixed points, thus natively supports safety and reachability specifications . The tool is intended to be used and extended by researches in the area of formal synthesis for complex systems.
