An algebraic Riccati equation is a type of nonlinear equation that arises in the context of infinite-horizon optimal control problems in continuous time or discrete time. The continuous time algebraic Riccati equation (CARE): $A^{T} X + X A - X B R^{- 1} B^{T} X + Q = 0} A n d t h e r e s p e c t i v e l i n e a r c o n t r o l l e r i s : \[K = R^{- 1} B^{T} P$ A solver receives A, B, Q and R and computes P and K.
