Model-Free Linear Quadratic Regulator
2021We review recent results on the convergence and sample complexity of the random search method for the infinite-horizon linear quadratic regulator (LQR) problem with unknown model parameters. This method directly searches over the space of stabilizing feedback gain matrices and, in spite of the lack of convexity, it converges to the globally optimal LQR

The Inconsistent Linear Quadratic Regulator
2021In this chapter we study a simple time-inconsistent version of the linear quadratic regulator in continuous time. Time inconsistency enters through an explicit dependence on the initial state for the final quadratic term. Loosely speaking, we want to control a system such that the final state is close to the initial point while at the same time keeping

Regression-Based Linear Quadratic Regulator
2018 IEEE International Conference on Robotics and Automation (ICRA), 2018We present the Regression-based Linear Quadratic Regulator (R-LQR), a new approach for determining locally-optimal control feedback policies for robots with non-linear dynamics and non-quadratic cost functions. Our proposal uses a free-derivative algorithm based on local quadratic regressions to obtain the robot motion policy.

Linear–Quadratic Regulator Problems
1995Abstract The “linear-quadratic regulator” (LQR) problem of optimal control has probably provided the greatest single stimulus for investigation of matrix Riccati equations in differential, difference, and algebraic forms. In this chapter the continuous and discrete LQR problems are to be outlined and then the solutions of these problems ...

Fractional Order Linear Quadratic Regulator
2008 IEEE/ASME International Conference on Mechtronic and Embedded Systems and Applications, 2008In this paper, we formulate the fractional linear quadratic regulator (LQR) problem. The analytical solution of fractional optimal control near the origin and infinity are derived. It is shown that the optimal control to the linear fractional system can be computed through the corresponding fractional Euler-Lagrange equations.

Jump linear quadratic regulator with controlled jump rates
IEEE Transactions on Automatic Control, 2001Summary: This note deals with the class of continuous-time linear systems with Markovian jumps. We assume that the jump rates are controlled. Our purpose is to study the jump linear quadratic regulator for this class of systems. The structure of the optimal controller is established.

Linear Quadratic Regulator for Autonomous Oscillation
2019 American Control Conference (ACC), 2019A recent result on eigenstructure assignment allows for a linear feedback control to achieve desired autonomous periodic behavior for linear plants, where the oscillation pattern is characterized by a frequency and mode shape (relative amplitudes and phase-offsets). We develop an optimal control theory based on the general result that parametrizes such

The Continuous-Time Linear Quadratic Regulator
2021In this chapter, we apply the dynamic programming theory to the continuous-time linear quadratic regulator problem (LQR). The LQR is a classical engineering problem and design technique in which a process has its settings optimized by minimizing a quadratic cost function.
