An Exact Penalty Method for Free Terminal Time Optimal Control Problem with Continuous Inequality Constraints

Journal of Optimization Theory and Applications, 2012
The authors consider a class of optimal control problems with free terminal time and continuous inequality constraints. They approximate the control function with a piecewise-constant function and transform the inequality constraints into terminal equality constraints for an auxiliary differential system.

Effects of the penalty mechanism against traffic violations in China: A joint frailty model of recurrent violations and a terminal accident

Accident Analysis & Prevention, 2020
A penalty mechanism is usually considered as a powerful means to reduce the probability of traffic violations and accidents by encouraging drivers to comply with traffic regulations. Penalty point and fine strategies are often used in parallel. Different degrees of penalty points and/or fines are imposed according to the specific violation behavior of ...

An exact penalty function algorithm for optimal control problems with control and terminal equality constraints, part 1

Journal of Optimization Theory and Applications, 1980
The presence of control constraints, because they are nondifferentiable in the space of control functions, makes it difficult to cope with terminal equality constraints in optimal control problems. Gradient-projection algorithms, for example, cannot be employed easily. These difficulties are overcome in this paper by employing an exact penalty function

Assignment of terminal penalties in controlling genetic regulatory networks

Proceedings of the 2005, American Control Conference, 2005., 2005
Probabilistic Boolean networks have been used to model inter-gene relationships and their dynamic behavior. Optimal control of such networks has been proposed by turning on or off individual genes. Though this problem was solved in an earlier work by using a dynamic programming algorithm, issues regarding the assignment of terminal penalties and ...

Nonlinear Model Predictive Control with Parameter-Dependent Terminal Penalty

2006 6th World Congress on Intelligent Control and Automation, 2006
We propose a quasi-infinite horizon nonlinear model predictive control with terminal inequality constraint and terminal state quadratic penalty. The feasibility of terminal state inequality constraint implies the states at the end of the horizon are in a prescribed asymptotically stable but not necessarily invariant ellipsoidal set in terms of an ...

Economic MPC without terminal constraints : gradient-correcting end penalties enforce asymptotic stability

Journal of process control, 2018
In recent years, economic MPC (EMPC) has gained popularity due to the promise of increasing performance by directly optimizing the performance index rather than tracking a given steady state. Moreover, EMPC formulations without terminal cost nor constraints are appealing for the simplicity of implementation.

Finite horizon H/sup infinity / control problems with terminal penalties

IEEE Transactions on Automatic Control, 1990
The authors generalize the standard H/sup infinity / control problem to the finite horizon case with two (possibly singular) terminal penalties at the initial and final times. The major objective of the generalization is to increase flexibility of H/sup infinity / controls; the terminal penalties correspond to treating an intrinsic issue of finite ...

A simple algorithm for the selection of terminal penalty weighting matrices

Journal of Guidance, Control, and Dynamics, 1986
One of the most basic tasks required in solving finite fixed-time linear- quadratic-regulator problems is the specification of a terminal penalty matrix. In theory, a matrix (frequently, a diagonal matrix) whose elements are large in an engineering sense is simply selected.
