Build a Hybrid Model

2-39

Double-click the Get Attribute block. The Get Attribute tab of the dialog box

contains a table. On the first row of the table, set Name to Value. Click OK. The

block acquires an extra signal output port, Value.

From the Servers library, drag the N-Server block into the subsystem window.

Double-click the N-Server block. Set Service time from to Signal port t. Click

OK. The block acquires an extra signal input port, t.

From the SimEvents Sinks library, drag an Entity Sink block into the subsystem

window.

From the Gateways library, drag a Timed to Event Signal block and an Event to

Timed Signal block into the subsystem window.

Connect and place the blocks as shown in Network Delay Subsystem Contents.

Navigate to the top-level view of the model. Select View > Navigate > Up to

Parent. Save the model.

Complete the Hybrid Model

Before you connect the newly created Network Delay subsystem block to complete the

hybrid model, simplify the top-level view of the original ABS model by grouping related

blocks. When you complete this procedure, the model looks as shown in Top-Level View of

Completed Hybrid Model.

To select both the Desired Relative Slip and ABS Controller blocks of the model,

hold down the left mouse button and drag the mouse. As you drag the mouse, a box

appears. Drag this box across a portion of both blocks. When you release the mouse

button, the two blocks are highlighted in blue.

Right-click one of the two highlighted blocks and select Create Subsystem from

Selection. The software places both blocks inside a new Subsystem block.

For the newly created Subsystem block, place the cursor in the text box that is

beneath the block. type the new name, ABS Controller.

To select both the Brake System Dynamics and Sensor Relative Slip blocks of the

model, hold down the left mouse button and drag the mouse. As you drag the mouse,

a box appears. Drag this box across a portion of both blocks. When you release the

mouse button, the two blocks are highlighted in blue.

Right-click one of the two highlighted blocks and select Create Subsystem from

Selection. The software places both blocks inside a new Subsystem block.

For the newly created Subsystem block, place the cursor in the text box that is

beneath the block. type the new name, Brake System Dynamics.
