APPROXIMATING SOLUTIONS FOR A CLASS OF STOCHASTIC FRACTIONAL LINEAR QUADRATIC OPTIMAL CONTROL PROBLEMS [PDF]
Analele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2018 In this paper we consider a linear quadratic control problem for a class of discretetime fractional order systems with multiplicative noise and we find lower bounds of the optimal cost and approximating solutions for the optimal control law.

Optimal Tracking Performance of MIMO Discrete-Time Systems with Network Parameters
Discrete Dynamics in Nature and Society, 2016 The optimal regulation properties of multi-input and multioutput (MIMO) discrete-time networked control systems (NCSs), over additive white Gaussian noise (AWGN) fading channels, based on state space representation, are investigated.

Taiwanese Journal of Mathematics, 2010 A structured doubling algorithm (SDA) for solving the discrete-time algebraic Riccati equation is developed for control systems with non-invertible control weighting matrices. The proposed SDA performs similarly to Newton's method here, but without Newton's additional cost of having to solve a Stein equation in each iteration.

IEEE Access, 2019 An optimal fault detection (FD) approach for a class of networked control systems (NCSs) is concerned in this work. To improve the accuracy of the FD, a new event-triggered scheme (ETS) is addressed, where the output measurement transmitted or not is ...

NGMV control of delayed piecewise affine systems [PDF]
, 2010 A Nonlinear Generalized Minimum Variance (NGMV) control algorithm is introduced for the control of piecewise affine (PWA) systems. Under some conditions, discrete-time PWA systems can be transferred into an equivalent state-dependent nonlinear system ...

MATLAB SIMULATIONS OF THE SOLUTION OF A LINEAR QUADRATIC CONTROL PROBLEM FOR A CLASS OF STOCHASTIC FRACTIONAL SYSTEMS WITH MARKOVIAN JUMPS [PDF]
Analele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2019 In this paper we apply the results in [7] concerning a finite-horizon, linear, quadratic optimal control problem for class of fractional order systems (FOS) with Markovian jumps to simulate the behaviour of the state variable of the system under the ...

A Discrete-Time Algorithm for the Resolution of the Nonlinear Riccati Matrix Differential Equation for the Optimal Control [PDF]
American Journal of Civil Engineering, 2014 The Riccati Matrix Differential Equation (RMDE) is an interesting equation in different fields of science and engineering practice. In fact, that the arithmetic solution for this matrix differential equation in the general case of varying-time matrices is very difficult to find.

Asian Journal of Control, EarlyView.Abstract The linear‐quadratic regulator (LQR) problem of optimal control of an uncertain discrete‐time linear system (DTLS) is revisited in this paper from the perspective of Tikhonov regularization. We show that an optimally chosen regularization parameter reduces, compared to the classical LQR, the values of a scalar error function, as well as the ...

Inertial‐Based LQG Control: A New Look at Inverted‐Pendulum Stabilization
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT Linear‐quadratic Gaussian (LQG) control is a well‐established method for optimal control through state estimation, particularly in stabilizing an inverted pendulum on a cart. In standard laboratory setups, sensor redundancy enables direct measurement of configuration variables using displacement sensors and rotary encoders. However, in outdoor
