Physical Signal Manipulation

Blocks for transmitting physical control signals

Physical Signal libraries contain blocks that transmit physical signals, organized by function. These blocks let you perform math operations or measurements on physical signals, model discrete behavior or discontinuities, and simulate physical sources.

Physical signals are different from regular Simulink® signals. Therefore, you need converter blocks to connect Physical Signal blocks to Simulink input and output ports. For more information, see Connecting Simscape Diagrams to Simulink Sources and Scopes.
