Case Study: Korea Institute of Machinery and Materials achieves 70% faster antirolling maglev prototype development with MathWorks Model-Based Design

KIMM Develops Prototype Maglev-Based Antirolling System for Mobile Harbors

The Korea Institute of Machinery and Materials (KIMM) needed to evaluate a maglev‑based antirolling system to stabilize catamaran‑style mobile harbors so containers could be unloaded safely in waves. Facing a hard three‑month deadline and the need for two complementary controllers (maglev gap control and active mass driver position control), KIMM used MathWorks' Model‑Based Design approach with MATLAB and Simulink and related products to avoid integrating disparate tools and to get the design right the first time.

Using MathWorks tools (Simulink, Simscape Multibody, Simulink Coder, Simulink Real‑Time, Simulink Design Optimization and Optimization Toolbox), KIMM modeled the platform and controllers, simulated and tuned the design, generated real‑time code, and ran the prototype on a PC/104 target. The MathWorks‑based workflow produced a working prototype in under three months, stabilized a 118 kg catamaran cross‑section with a 4.1 kg moving mass in about 5 seconds, reduced development time by ~70% (from an estimated 10+ months), saved $20,000+ in prototyping costs, and delivered simulation results within ~10% of measured performance.
