In this paper we consider the problem of air to ground missile guidance system using fuzzy controller which uses Proportional Navigation and Pure Pursuit methods. The fuzzy controller’s rules are defined using Tabu Search (TS). The missile model is assumed as three degree of freedom (3DOF) (assuming the analysis in the vertical plane only). This paper presents numerical results for applying the...

The problem of designing a controller to meet different specifications or deciding that no such controller exists is addressed in this paper by linking three types of tools: the Youla parameterization allows searching for a controller in a convex set; formulations using Linear Matrix Inequalities (LMI) are proposed for different practical specifications; the corresponding convex problem is solv...

We present a switching approach for the stabilization of the strongly damped inverted pendulum cart system, provided that the pendulum is initialized inside of the upper-half plane, and the linear viscous force is known. The control strategy uses two stabilizing controllers. The first is a nonlinear controller, devoted to bringing the pendulum very close to its unstable equilibrium point. Then,...

The paper deals with the problem of sampled-data polynomial modal control for a linear continuous-time periodic plant with delays at the input and the output of the sampled controller. It is assumed that the plant and the digital controller have the same period. The characteristic matrix of the closed-loop system is constructed. An algorithm is given for constructing the set of causal discrete-...

This paper provides a novel hierarchical control for VSI-based microgrids. The advantage of the provided control scheme is to maintain the frequency and voltage stability and load sharing against large-signal disturbances. A hierarchical control, consisting of three levels, is described. A new control loop based on PI controller, is presented. The new control loop has a great impact on increasi...

This paper presents an approach to controller design in the complex plain, satisfying some performance specifications and an analysis of the obtained system in the presence of parametric uncertainty. The relative location of regions in the complex plane, specifying performance and uncertainty, is analyzed. Transient responses and the notion of robustness are commented. The design example, shown...

In this paper, the problem of designing fixed-order robustH∞ controllers is considered for linear systems affected by polytopic uncertainty. A polynomial method is employed to design a fixed-order controller that guarantees that all the closed-loop poles reside within a given region of the complex plane. In order to utilise the freedom of the controller design, an H∞ performance specification i...

Plane perching on a wire has been demonstrated with success in laboratory conditions by [Cory & Tedrake, 2008]. The present paper focuses on designing a controller for a small wall landing glider. We use a simulator and a reinforcement learning algorithm in a coarsely discretized state-space to design an optimal control for the landing. Analysis of this policy allows us to deduce a simpler clos...

Electric vehicles with independently controlled drivetrains allow torque vectoring, which enhances active safety and handling qualities. This article proposes an approach for the concurrent control of yaw rate sideslip angle based on a single-input single-output (SISO) controller. With SISO formulation, reference is first defined according to vehicle requirements then corrected actual angle. Th...
