New features and changes introduced in this version are

• Improved Fundamental and Controllable Friction Clutch Mode Logic

• Physical Modeling of Mechanical Friction

Improved Fundamental and Controllable Friction Clutch Mode Logic

The Fundamental Friction Clutch and Controllable Friction Clutch blocks now have additional state transitions to prevent the Clutch from getting stuck in either Wait state. The Clutch can now transition directly from Wait Forward to Wait Reverse and vice versa. This change in clutch logic might lead to changes in simulation results, compared to results produced by earlier versions. If they differ, the new results are more accurate.

Physical Modeling of Mechanical Friction

A recent MATLAB Digest article explains how to simulate mechanical friction with Simulink, SimDriveline™, and SimMechanics™ models. A set of models accompanies the article in a compressed zip archive available from MATLAB Central. In the MATLAB Desktop File Exchange tool, search for "Mechanical Friction with Simulink and Physical Modeling".
