The parameters to be optimized in an off-line manner are the covariance matrices of state and measurement noises Q and R, respectively. The optimal values of the above covariance matrices are injected into EKF in an on-line manner to estimate states. The suggested approach is demonstrated using a computer simulation of two-link manipulator. Finally, simulations and comparison with particle swarm optimization (PSO) show the effectiveness of proposed method, and exhibit a more superior performance than its conventional counterpart.
