Bobsled Example <Bobsled.doc> Page 1 Define the A and B matrices in terms of the parameters % Bobsled_AB.m This file defines the A, B matrices. % % Parameters in SI units M1= 45.4; M2= 90.8; alpha= 0.1745; K= 17520; B0= 17.5; B1= 87.6; B12= 0.0; Lf= 0.305; g= 9.81; % % Matrices A(1,:)= [ -(B0+B12+B1)/M1, (B0+B12)/M1, -K/M1 ]; A(2,:)= [ (B0+B12)/M2, -(B0+B12)/M2, K/M2 ]; A(3,:)= [ 1, -1, 0 ]; % B= [ 1, K/M1 ; 1, -K/M2 ; 0, 0 ]; % % Since U is constant evaluate it here U= [ g*sin(alpha); Lf ]; % Define the state equations operationally function xdot= BobsledEqs(t,x) % This file defines the Bobsled equations in terms of A and B. U is constant. % % Parameters A= [ -2.3150 0.3855 -385.9031 ; 0.1927 -0.1927 192.9515 ; 1.0000 -1.0000 0 ]; % B= [ 1.0000 385.9 ; 1.0000
