Nuclear fusion reactors offer a promising approach to clean energy production. The design of a tokamak reactor employs external magnetic fields to confine a plasma in a toroidal shape, while external heating mechanisms bring it to thermonuclear conditions. Effective control of plasma temperature, density, and magnetic topology is crucial and requires high-performance systems. Central to this control is the plasma control system, which demands a comprehensive, methodical design and deployment plan before reaching application. In recent years, the Plasma Control System Simulation Platform has served as the pivotal framework for this strategy. This PCSSP is based on Simulink© and provides an environment to standardize the way controller and plant models are set up, simulated, deployed, and tested systematically and periodically. This contribution will summarize the PCSSP environment, its recent considerable upgrades, and its central role in PCS design, deployment, and operation.
