Relation between Model Feedback Control Systems and Parameterization of All Stabilizing Controllers

چکیده
In the present paper, we examine model feedback control systems. Because model feedback control is simple, the model feedback control system has been applied in many applications such as the trajectory control of robot manipulators, serially connected tanks, etc. The control structure of the model feedback control system is limited, and nothing has been reported about whether or not model feedback control can represent all of the stabilizing controllers of a plant. The purpose of the present paper is to give a solution to the question as to whether or not all stabilizing controllers for a plant are expressible in the model feedback control structure. For strictly proper systems, the relation between model feedback control and the parameterization of all stabilizing controllers for minimum phase systems is shown. A simple design method to specify control characteristics is also presented.

A Parameterization of Stabilizing Controllers over Commutative Rings
In this paper we are concerned with the factorization approach to control systems, which has the advantage that it embraces, within a single framework, numerous linear systems such as continuous-time as well as discrete-time systems, lumped as well as distributed systems, 1-D as well as n-D systems, etc.[1]. The factorization approach was patterned after Desoer et al.[2] and Vidyasagar et al.[1...
متن کاملParameterization of Stabilizing Controllers with Integral Action - Automatic Control, IEEE Transactions on
In the standard linear time-invariant multi-input/multioutput unity-feedback system, a parameterization of stabilizing controllers with integral action is obtained. These controllers guarantee asymptotic tracking of step reference inputs at each output channel with zero steady-state error.

In cruise control systems, the performance of the controller is important. Hence, in order to have accurate results, the nonlinear behavior of a vehicle model should also be considered. In this article, a vehicle with a nonlinear model is controlled by using a nonlinear method. The nonlinear term of the model is the generated torque of engine, which is a polynomial equation. In addition, feedba...
متن کاملThe parameterization of all robust stabilizing simple repetitive controllers for multiple-input/multiple-output plants
The simple repetitive control system proposed by Yamada et al. is a type of servomechanism for the periodic reference input. That is, the simple repetitive control system follows the periodic reference input with small steady state error, even if a periodic disturbance or uncertainty exists in the plant. In addition, simple repetitive control systems make transfer functions from the periodic re...
متن کاملController parameterization for SISO and MIMO plants with time delay
Controller parameterization is a very fundamental problem in control theory. It provides an elegant and efficient way towards solving the stabilizing and design problem, with which all stabilizing controllers are characterized and thus a constrained design procedure can be replaced by an unconstrained optimization. In this paper we deal with the problem of characterizing all stabilizing control...
