Research Guide
What is Real-time simulation and control systems?
Real-time simulation and control systems are technologies that enable digital computers to simulate and control dynamic systems in real time, particularly for power systems using Hardware-in-the-Loop (HIL) simulation, FPGA-based emulation, and digital simulation of power electronics, electrical systems, and renewable energy applications.
This field encompasses 57,745 works focused on real-time simulation for power systems, control systems, electric drives, and smart grid development. Key methods include Hardware-in-the-Loop simulation, FPGA-based emulation, and digital simulators for electrical systems. Growth data over the past 5 years is not available.

Real-time simulation and control systems support applications in power delivery infrastructure for smart grids, as described in "Toward a smart grid: power delivery for the 21st century" (2005) by S. Massoud Amin and B.F. Wollenberg, which addresses security, agility, and robustness against new threats with 1590 citations. In aerospace, "The Digital Twin Paradigm for Future NASA and U.S. Air Force Vehicles" (2012) by Edward H. Glaessgen and David S. Stargel outlines digital twins for lighter mass vehicles under higher loads, cited 2178 times. Autonomous vehicles benefit from high-fidelity simulations like AirSim in "AirSim: High-Fidelity Visual and Physical Simulation for Autonomous Vehicles" (2017) by Shital Shah et al., with 1999 citations.
Reading Guide
Where to Start
"Digital control of dynamic systems" by Gene F. Franklin, M. L. Workman, and Dave Powell (1980) provides the foundational treatment of digital computers in real-time control with emphasis on design for good dynamic response using sampled signals, making it ideal for beginners with its 3195 citations.
Key Papers Explained
"Digital control of dynamic systems" (1980) by Franklin et al. establishes digital control basics, which "Feedback Control of Dynamic Systems" (1986) by Franklin, Powell, and Emami-Naeini extends with classical and state-space methods for real-time design (2309 citations). "Power system control and stability" (1979) applies these to power systems stability (2604 citations), while "Modern Control Engineering" (2010) by Singh et al. updates engineering practices (2192 citations). "The Digital Twin Paradigm for Future NASA and U.S. Air Force Vehicles" (2012) by Glaessgen and Stargel builds on simulation for advanced vehicles (2178 citations).
