    Below are the information for the Kalman filter assignment. The question 1 consist of a theoretical part where from the y and z positions and the y and z components of velocity, the state vector and measurement vector needs to be writen. For a kinematic propagation model, the matrices needs to be determined, measurement model, propagation covariance and measurement covariances as well.Every aspect needs to be mathematically developped (for an easy understanding)An example of the of what is required is given page 37 (slides 162 to 164) but it need further explanation.of the &quot;Sensor & data fusion&quot; ch4-6-2014&quot; Question 2 consist of creating a Kalman filter in Matlab following the algorithm example given in page 28 (Slide 145) or page 48 (Slide 184) Justifying the use of that method over the algorithm 1 (The Matlab code must be also explained briefly). Then using the data given on the file SDF2013a.txt prove that it is working. Question 3 Add rate to the measurement vector previously found and justify teh revised filter design (including initialisation) and evaluate the effect of the change on the position estimates obtained with the data of SDF2013b.txt. Assume the range rate measurement model is R(dot) = - z(dot)sin alpha, where sin alpha =0.13100062Question 4. The north-south motion can be approximated by simple harmonic motion with angular frequency omega = 2 Pi / Tday, where Tday = 86164 s (1 sidereal day). Use this to develop a model for a dynamics-based propagation model of the z and dz/dt components, modify the filter of part 3 with this change, and then use the new filter to re-process the data of SDF2013b.txt. Show and discuss the results.

    A Reaction Wheel Pendulum is a standard topic in most physics courses because it includes some physical subjects such as the simple harmonic motion, the period of oscillation, the acceleration of gravity, the center of mass, the moment of the inertia and momentum. The reaction wheel pendulum adopted in this project has a motorized propeller at the center of wheel so it can lift the pendulum after given voltage. This concept of pendulum system is useful and can be applied in real life. The reaction wheel pendulum system has many applications such as measurement, scholar tuning, coupled pendulum and entertainment.The control problem in driven pendulum system is controlling the pendulum behavior, such as the stability, rise time and overshoots with adjusting the given voltage.LQR controller is Linear-quadratic (LQ) state- feedback regulator for state-space system, appropriate matrix Q and R to enable system to achieve optimal stability by modifying weights in the matrix Q and R corresponding variables. The purpose of this project is to design LQR for stabilizing a reaction wheel pendulum. The pendulum with this controller reaches a steady-state angle with desired transient response.

    Reaction wheel pendulum or known inertia wheel pendulum as is similar to inverted pendulum but this reaction wheel pendulum using a dc motor which is attached to its reaction wheel or disk.In this project there are two main things which need to control there are - swing up control and stabilization control when the pendulum is at an upright position by using Linear Quadratic Regulator (LQR).This is the example video of Reaction Wheel Pendulum...

The non linear version is required to estimate the impact of acceleration due to centripetal forces. The job is to formulate the motion, create the optimal filter formula, run a matlab simulation to show the results. And also recommend the sampling rate.
