the problem in this system is non-linearity that is why the riccati equation is hard to solve

i need only matrix K for a given matrices the riccati equation is A'K-KA-Q+KBR-1 B'K=0

i need help please

How to find matix K (Riccati equatin) <<<<<< pleas help me

[SIZE="5"]no one want to help me?

[SIZE="3"]First, thank you for your reply, secondly I want to know if this approximations (p2 and p3) are not valid or horrible as you say, what is your advice for me to do? and why ΔA3 =0

[SIZE="5"]taking the Taylor expansion of Eqn , [SIZE="4"] i mean equations ( X'1 to X'8 ) [SIZE="4"]after that Taylor expansion has been taken like that ΔX'={ A0 + ΔA1(ΔX1)+ΔA3(ΔX3)+ΔA11(ΔX1^2))ΔX+B0 Δu → ( xx) [SIZE="4"] i don't understand equation ( xx = taylor expansion )...

please help me

hi everyone , i don't understand these steps for Taylor Expansion , it has used for state space equations the equations are the approximations for sin and cos the equation for Taylor series is ( i don't understand at all ) please help me if you can

no one help

x2 dx2+(x2+ cos x1 ) dx1=0 take integration plese help

:frown: how u can take integration for both side

this is nonlinear control system pleas help
