What is Modeling and Simulation Systems?
Modeling and Simulation Systems is a computational framework centered on the Modelica language and environment that supports object-oriented modeling, co-simulation, and simulation of cyber-physical systems through equation-based languages.
The field encompasses 22,312 works focused on Modelica for object-oriented modeling, hybrid modeling, real-time systems, and mechatronic systems. It enables equation-based languages and co-simulation of cyber-physical systems. Growth data over the last 5 years is not available.
Topic Hierarchy
Research Sub-Topics
Modelica Language for Object-Oriented Modeling
This sub-topic covers the syntax, semantics, and extensions of the Modelica language for acausal, equation-based modeling of complex systems. Researchers develop libraries and tools for multi-domain physical modeling.
Co-Simulation with Functional Mock-up Interface
This sub-topic examines FMI standards and algorithms for interoperable co-simulation of heterogeneous models from different tools. Researchers address synchronization, stability, and real-time constraints in distributed simulations.
Hybrid System Modeling in Modelica
This sub-topic focuses on modeling discrete events, state machines, and continuous dynamics interactions using Modelica's when-clauses and hybrid solvers. Researchers study event handling and numerical robustness.
Real-Time Simulation with Modelica
This sub-topic investigates code generation, fixed-step solvers, and hardware-in-the-loop setups for real-time Modelica simulations. Researchers optimize for deterministic execution in embedded controllers.
Cyber-Physical Systems Simulation
This sub-topic explores integrated modeling of software, networks, and physical components in Modelica for CPS analysis. Researchers tackle co-design, fault injection, and scalability challenges.
Why It Matters
Modeling and Simulation Systems support simulation of complex cyber-physical and mechatronic systems across engineering applications. For example, MuJoCo: A physics engine for model-based control by Todorov et al. (2012) provides a physics engine for multi-joint dynamics and contact responses, used in 4233 cited works for model-based control in robotics. Numerical Solution of Initial-Value Problems in Differential-Algebraic Equations by Brenan et al. (1995) addresses DAEs in applications like chemical processes, cited 3384 times for solving stiff problems in industrial simulations. These tools enable accurate real-time modeling in mechatronics and control systems.

Where to Start
"Feedback systems: an introduction for scientists and engineers" by Åström and Murray (2008) provides foundational principles for feedback in physical systems, essential before tackling simulation-specific papers.
Key Papers Explained
Han (2009) in "From PID to Active Disturbance Rejection Control" introduces error-driven control extended by observers, building foundations used in Todorov et al. (2012) "MuJoCo: A physics engine for model-based control" for dynamics simulation. Brenan et al. (1995) "Numerical Solution of Initial-Value Problems in Differential-Algebraic Equations" advances DAE solving critical for Modelica's equation-based models, complemented by Hairer et al. (1987) "Solving Ordinary Differential Equations I" for ODE methods. Soetaert et al. (2010) "Solving Differential Equations in R: Package deSolve" applies these to practical tools.
