Simultaneous Linear Quadratic Pole Placement (lqpp) Control Design
نویسنده
چکیده
The pole placement (PP) technique for design of a linear state feedback control system requires specification of all the closed-loop pole locations even though only a few poles dominate the system’s transient response characteristics. The linear quadratic regulator (LQR) method, on the other hand, optimizes the system transient response and does not directly impose the location of the dominant poles. This paper presents a new optimal linear quadratic pole placement (LQPP) technique that simultaneously assigns some poles to exact desired dominant locations (partial pole placement) and adjusts the rest of the poles to optimize an LQ performance index (parametric optimization). As a result, a designer can fashion his control design to benefit from the PP and LQ techniques. The paper only addresses the LQPP technique for a single-input full-state feedback control system.

The smart structure modeling and control design is carried out using MATLAB software in state space form. Subs...
متن کاملSimultaneous pole placement and optimal state or output feedback controller design
In this paper, inverse optimal control theory is used to design a state or an output feedback controller that both places the closed loop poles at desired positions and satisfies a linear quadratic criterion. The design method consists of two steps, first n-m poles are precisely placed and second the remaining m poles are selected to satisfy optimality criteria, where n is the number of the sys...
متن کاملPredictive pole-placement control with linear models
The predictive pole-placement control method introduced in this paper embeds the classical pole-placement state feedback design into a quadratic optimisation based model-predictive formulation. This provides an alternative to model-predictive controllers which are based on linear-quadratic control. The theoretical properties of the controller in a linear continuous-time setting are presented an...
متن کاملAdaptive fuzzy pole placement for stabilization of non-linear systems
A new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. We use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. Then, we linearized this identified model at each sampling time to have an approximate linear time varying system. In order to stabilize...
