 Models
 
+- Power-Split HEV system model is refactored to clean up.
+  Previously two separate system models existed
+  for speed tracking simulation and direct torque input simulation.
+  They are now merged into one.
 - Battery block from Simscape Electrical is added as
   a new referenced subsystem for High-Voltage Battery component.
   The previous model is included as well.
