Traditional system design has used extensive testing to verify behavior, but testing is capable of only finite conclusions. If a real-time simulation or physical prototype of the system is available, you can perform real-time testing of your control algorithm by Requirements Engineering (RE) is often seen as a preliminary phase to design, however in a PLM (Product Life-cycle Management) context its range widens to the whole life cycle of a product.
