Managing Multi-Mode Tasks with Time Cost and Quality Levels using Optimal Discrete Control Synthesis
15 years 11 months ago
Real-time control systems are complex to design, and automation support is important. We are interested in systems with multiple tasks, each with multiple modes, implementing a fu...
