Integrator transfer function
Discrete Time Integrator The Discrete-Time Integrator block implements discrete-time integration or accumulation of the input signal. The block can integrate or accumulate using the Forward Euler, Backward Euler, and Trapezoidal methods. In integration mode, is the block's sample time. In accumulation mode, .The block's sample time determines when the block's output signal is computed.Use blocks from the Continuous library to model differential equations. You can take the time derivative of a signal. You can integrate or delay a signal. You can model PID controllers and linear systems using transfer function or state-space representations.
