Description

Use this block to update the motion state of a platform in a UAV scenario simulation with input signals at each time step. The block takes the position, orientation, velocity, acceleration, and angular velocity as inputs to update the motion state bus of the specified platform. However, this block does not move the platform based on velocity and acceleration inputs as there is no kinematic model being simulated in the UAV Scenario.

To use this block, ensure that UAV Scenario Configuration block is in your model.

This block uses the sample time specified in the UAV Scenario Configuration block.

Examples

Simulate UAV Scenario Using Scenario Blocks

Use the UAV scenario blocks to simulate a scenario in Simulink®.

Limitations

The UAV Scenario blocks do not support:

• Code generation

• Model reference

• Multiple instances of the UAV Scenario Configuration block

• Rapid acceleration mode

In addition, the execution order is important when using these blocks in a closed loop simulation. The UAV Scenario Configuration block must execute first. The UAV Scenario Motion Write block must execute before the UAV Scenario Motion Read, UAV Scenario Lidar, and UAV Scenario Scope blocks.
