These files allow the simulation of a differential steered (unicycle-like) mobile robot considering its complete dynamic model. The dynamic model here adopted is based on velocities (not torques), which makes it easier to integrate with existing mobile robot controllers that generate references for linear and angular velocities.
Although not required, the blocks were built to be compatible with Peter Corke's Robotics Toolbox, so the user can make use of the toolbox functions.
Sets of dynamic parameters are available for the following robots:
- Pioneer 3-DX with Sick LASER sensor;
- Pioneer 3-DX without LASER sensor;
- Pioneer 2 without on-board computer (no LASER sensor);
- Pioneer 2 with on-board computer (no LASER sensor);
- Robotic wheelchair carrying a 55kg person;
- Robotic wheelchair carrying a 125kg person;
- Khepera III (LAUT, 2011);
- RobuLAB-10 (SHOJAEI et al., 2011).

The files include two libraries:

- "DiffSteer_model.slx": contains the kinematic and dynamic blocks of the differential-drive mobile robot.

- "Controllers.slx": contains the following blocks:
a) trajectory tracking kinematic controller;
b) dynamic compensation controller 1;
c) dynamic compensation controller 2;
d) dynamic parameters estimator (for adaptive controllers);
e) trajectory generator;
f) performance calculator (IAE, ITAE, ISE, ITSE and energy indexes).

Four Simulink systems are provided as examples:

1. "kinematic_controller_system.slx": implements a simple trajectory tracking controller using both kinematic and dynamic blocks of the robot.

2. "dynamic_controller_system.slx": implements a more complex system that includes an adaptive dynamic compensation controller and the trajectory tracking controller with noisy sensor measurements.

Note: After running "kinematic_controller_system.slx" or "dynamic_controller_system.slx" simulations you can check the results running the included script "plot_results.m".

3. "sl_lanechange_unicycle.slx": implements the same system as the Robotics Toolbox "sl_lanechange", but using the kinematic model of the differential steered mobile robot.

4. "sl_lanechange_unicycle_dynamics.slx": implements the same system as the Robotics Toolbox "sl_lanechange", but using the kinematic and the dynamic models of the differential steered mobile robot.

Also, the following scripts are provided:

1. "sim_kin_controller.m": uses the "kinematic_controller_system.slx" system to simulate a kinematic trajectory tracking controller acting on a mobile robot (complete model).

2. "sim_dyn_controller.m": uses the "dynamic_controller_system.slx" system to simulate an adaptive dynamic compensation controller operating with the trajectory tracking controller acting on a mobile robot (complete model).

3. "plot_results.m" and "plot_results_kin.m": present the results of the simulations.

All blocks were tested in MATLAB R2012b, R2013a, R2014b, R2016a and 2017a, all under Windows.
