چکیده

A computationally efficient technique for the numerical solution of optimal control problems is discussed. This method utilizes tools from nonlinear control theory to transform the optimal control problem to a new, lower dimensional set of coordinates. It is hypothesized that maximizing the relative degree in this transformation is directly related to minimizing the computation time. Firm evidence of this hypothesis is given by numerical experiments. Results are presented using the Nonlinear Trajectory Generation (NTG) software package.

Inversion of Gravity Data by Constrained Nonlinear Optimization based on nonlinear Programming Techniques for Mapping Bedrock Topography

A constrained nonlinear optimization method based on nonlinear programming techniques has been applied to map geometry of bedrock of sedimentary basins by inversion of gravity anomaly data. In the inversion, the applying model is a 2-D model that is composed of a set of juxtaposed prisms whose lower depths have been considered as unknown model parameters. The applied inversion method is a nonli...

Near-Optimal Trajectory Generation for Omni-directional Vehicles by Constrained Dynamic Inversion

This paper presents a computationally cheap algorithm for near-optimal trajectory generation in presence of control constraints. We consider the problem of moving an omnidirectional vehicle from a specified initial state to a desired final state while maintaining a good trade-off between the maneuver time and the final state-error. A parameterized spline that satisfies the boundary conditions o...

Improved depth imaging by constrained full-waveform inversion

We propose a formulation of full-wavefield inversion (FWI) as a constrained optimization problem, and describe a computationally efficient technique for solving constrained full-wavefield inversion (CFWI). The technique is based on using a total-variation regularization method, with the regularization weighted in favor of constraining deeper subsurface model sections. The method helps to promot...
