نویسندگان
چکیده
Nonlinear control allocation is an important part of modern nonlinear dynamic inversion based flight systems which require a highly accurate model aircraft aerodynamics. Generally, accurately implemented onboard determines how well the system nonlinearities can be canceled. Thus, more results in better cancellation, leading to higher performance controller. In this paper, presented that combines with piecewise multilinear representation allocation. The developed through generalization Kronecker product for block matrices, combined canonical linear functions. Analytical expressions Jacobian are also presented. proposed formulation gives equivalent analytical aerodynamic data and thus capable modeling aerodynamics over entire envelope aircraft. resulting controller applied tailless flying wing ten independently operating surfaces. simulation two innovative surface configurations indicate achieved, tracking compared methods on multivariate polynomials splines.

Model predictive control of nonlinear systems using piecewise linear models
We consider the problem of controlling nonlinear systems which are modeled as a set of piecewise linear (PL) or affine systems using model predictive control (MPC). The paper reviews recent results on the analysis and control of PL systems, which can model a wide range of practically relevant nonlinear systems. Using techniques from the theory of linear matrix inequalities (LMIs), we develop a ...
متن کاملPiecewise Multilinear Sparse Grid Interpolation in MATLAB
To recover/approximate smooth multivariate functions, sparse grids are superior to full grids due to a significant reduction of the required support nodes. The order of the convergence rate in the maximum norm is hereby preserved up to a logarithmic factor. We describe three possible piecewise multilinear interpolation schemes in detail and conduct a numerical comparison. Furthermore, we summar...

A control-Lyapunov approach is used to develop an adaptive optimizing control allocation algorithm for over-actuated mechanical systems where the actuator model is a¢ ne in the uncertain parameters. Uniform global (asymptotic) stability is guaranteed by the control allocation de ned by the dynamic update laws in combination with an exponentially stable controller.
