It is the purpose of this study to develop an economical Robust design methodology for micro-scale secondary flow control in compact inlet diffusers. To illustrate the potential of economical Robust Design methodology, two different mission strategies were considered for the subject inlet, namely (1) Maximum Performance, and (2) Maximum HCF Life Expectancy. The Maximum Performance mission maxim...

This paper discusses the design of optimal feedback control laws for hybrid systems with autonomous (continuous) modes. The solution of similar problems, when the dynamic modes are non linear, is, in general, dependent on the initial conditions. The same problem affects the ”open loop” control based on the definition of the optimal switching times. In this work an algorithm is proposed, allowin...

This paper investigates the stochastic linear quadratic (LQ, for short) optimal control problem of Markovian regime switching system. The representation cost functional LQ system is derived by technique Itô’s formula with jumps. For system, we establish equivalence between open-loop (closed-loop, resp.) solvability and existence an adapted solution to corresponding forward-backward differential...

This paper considers the problem of real-time mode scheduling in linear time-varying switched systems subject to a quadratic cost functional. The execution time of hybrid control algorithms is often prohibitive for real-time applications and typically may only be reduced at the expense of approximation accuracy. We address this trade-off by taking advantage of system linearity to formulate a pr...

OPTCON is an algorithm for the optimal control of nonlinear stochastic systems which particularly applicable to economic models. It delivers approximate numerical solutions optimum (dynamic optimization) problems with a quadratic objective function models additive and multiplicative (parameter) uncertainties. The was first programmed in C# then MATLAB. allows deterministic control, latter open ...

We present an open-loop optimal control approach to treat the optimal trajectory planning problem for nonholonomic wheeled mobile robots in the presence of kinematics and dynamics of both wheels and manipulators. This method is based on the Pontryagin's minimum principle that by providing a two point boundary value problem is solved the problem. The specific problem considered is that controlli...

We consider a stochastic linear–quadratic (LQ) problem with possible indefinite cost weighting matrices for the state and the control. An outstanding open problem is to identify an appropriate Riccati-type equation whose solvability is equivalent to the solvability of this possibly indefinite LQ problem. In this paper we introduce a new type of differential Riccati equation, called the generali...

This paper presents a survey on quantum control theory and applications from a control systems perspective. Some of the basic concepts and main developments (including open-loop control and closed-loop control) in quantum control theory are reviewed. In the area of open-loop quantum control, the paper surveys the notion of controllability for quantum systems and presents several control design ...

1.1 Overview In this book chapter a comparative assessment of modelling and control of mechanical manipulator is considered. First, kinematic and dynamic modelling of wide range of mechanical manipulators comprising flexible link, flexible joint and mobile manipulators are considered. Then, open-loop optimal control problem is formulated to control of the obtained system. Finally, some applicat...
