Optimal Control and Estimation

Optimal Control and Estimation Project description The writer should use matlab software to solve this problem and he/she should explain the code. ---------- Added on 25.11.2014 20:41 1 Problem I Using a least-square algorithm, t quadratic and cubic polynomials to the following time series of the variable z : 1 ; 27 ; 33 ; 45 ; 12 ; 16 ; 83 ; 67 ; 54 ; 39 ; 23 ; 6 ; 14 ; 15 ; 19 ; 31 ; 37 ; 44 ; 56 ; 60 : (1) Compute the mean-square error in both cases, and plot the results. 2 Problem II Repeat Problem I, assuming that each point has a dierent weight in the least square estimation procedure. In particular, the rst data point is 20 times better than the last, the second data point is 19 times better, and so on. 3 Problem III One more piece of data is to be added to the sequence in Problem I. Assuming equal weighting of all points. How would a new reading of 25 aect the quadratic curve t? Use a recursive least-square estimator to nd the answer. 4 Problem IV Apply a recursive least square estimator to the entire time series of Problem I, that is, compute a running estimate beginning with the rst point and ending with the last. 5 Problem V The vector x is related to the vector y by the following equation, x 1 x 2 = 0 1 3 4 y 1 y 2 : (2) 1 Given the following noisy measurements z = y + n , what is the least- square estimate of x ? z 1 = 0 ; 1 ; 7 ; 8 ; 5 ; 7 ; 9 ; 10 ; 6 ; 4 z 2 = 10 ; 7 ; 4 ; 5 ; 5 ; 3 ; 0 ; 2 ; 2 ; 4 2 PLACE THIS ORDER OR A SIMILAR ORDER WITH US TODAY AND GET AN AMAZING DISCOUNT :)
