  • Manual Switch block

Description

TheManual Switchblock is a toggle switch that selects one of its two inputs to pass through to the output. To toggle between inputs, double-click the block. You control the signal flow by setting the switch before you start the simulation or by changing the switch while the simulation is executing. TheManual Switchblock retains its current state when you save the model.

To programmatically toggle the switch, set theset_paramswproperty to'0'要么'1'. For example, to connect the second input to the output:

set_param（gcb，'sw'，'0'）

要将第一个输入连接到输出：

set_param(gcb,'sw','1')

Note

Double-clicking theManual Switchblock does not open the block dialog box. Instead, it toggles the input choice.

要查看块参数，请右键单击块并选择Block Parameters (ManualSwitch).

Select this check box to allow inputs with different sizes and propagate the selected input signal size to the output signal. If you clear the box, the block expands scalar inputs to have the same dimensions as nonscalar inputs. SeeScalar Expansion of Inputs and Parameters.

Modeling a Fault-Tolerant Fuel Control System

Combine Stateflow® with Simulink® to efficiently model hybrid systems. This type of modeling is particularly useful for systems that have numerous possible operational modes based on discrete events. Traditional signal flow is handled in Simulink while changes in control configuration are implemented in Stateflow. The model described below represents a fuel control system for a gasoline engine. The system is highly robust in that individual sensor failures are detected and the control system is dynamically reconfigured for uninterrupted operation.
