Mean-Square H∞ Filter Design: Application to a 2DOF Helicopter
نویسندگان
چکیده
This paper designs the central finite-dimensional H∞ filter for linear stochastic systems with integralquadratically bounded deterministic disturbances, that is suboptimal for a given threshold γ with respect to a modified BolzaMeyer quadratic criterion including the attenuation control term with the opposite sign. The original H∞ filtering problem for a linear stochastic system is reduced to the corresponding mean-square H2 filtering problem, using the technique proposed in [1]. In the example, the designed filter is applied to estimation of the pitch and yaw angles of a two degrees of freedom (2DOF) helicopter.

Mean-square H∞ filtering for stochastic systems: Application to a 2DOF helicopter
This paper designs the central finite-dimensional H1 filter for linear stochastic systems with integral-quadratically bounded deterministic disturbances, that is suboptimal for a given threshold g with respect to a modified Bolza–Meyer quadratic criterion including the attenuation control term with the opposite sign. The original H1 filtering problem for a linear stochastic system is reduced to...
متن کاملModel predictive control of 2DOF helicopter
This paper deals with model predictive control (MPC) approach for a 2 DOF (degree of freedom) helicopter. The main objective is to stabilize beam of the 2DOF helicopter with respect to pitch and yaw angles. Development of controller for 2DOF helicopter is challenging because of its coupling effects between two axes and also due to its highly nonlinear characteristics. An accurate model of the s...
متن کاملIntelligent Auto pilot Design for a Nonlinear Model of an Autonomous Helicopter by Adaptive Emotional Approach
There is a growing interest in the modeling and control of model helicopters using nonlinear dynamic models and nonlinear control. Application of a new intelligent control approach called Brain Emotional Learning Based Intelligent Controller (BELBIC) to design autopilot for an autonomous helicopter is addressed in this paper. This controller is applied to a nonlinear model of a helicopter. This...
متن کاملApplication of Two-degree-of-freedom Control to Electrodynamic Shaker Using Adaptive Filter Based on H∞ Filter
In this paper, we propose a method of applying a two-degreeof-freedom (2DOF) control with adaptive filter since such control of an electrodynamic shaker that is not permitted to employ the iteration control method. At first, a mathematical model and an uncertainty weighting are introduced, and a feedback controller is designed using μ-synthesis. 2DOF controller is constituted. Next, an adaptive...
متن کاملCircular Mean Filtering For Textures Noise Reduction
In this paper, a special preprocessing operations (filter) is proposed to decrease the effects of noise of textures. This filter using average of circular neighbor points (Cmean) to reduce noise effect. Comparing this filter with other average filters such as square mean filter and square median filter indicates that it provides more noise reduction and increases the classification accuracy...
