A Flexible Generalized Minimum Variance Controller for MIMO Time-Varying Systems
نویسنده
چکیده
A generalized minimum variance controller is developed for servo application for multiple input and multiple output systems having time-varying dynamics. The plant to be controlled is a controlled autoregressive moving average model and the control objective is to minimize a generalized minimum variance performance index that is an extension of the standard index from linear time invariant cases for linear timevarying applications. Key-Words: Multiple variable systems, generalized minimum variance control, time-varying systems.

A generalised minimum variance controller for time-varying MIMO linear systems with multiple delays
In this paper we study optimal control of time-varying multi-input multi-output stochastic systems and develop a generalised minimum variance controller. The system to be controlled is described using a multiinput multi-output time-varying autoregressive moving average model that has multiple delays between the output and input. The controller minimises the sum of output tracking error variance...

متن کاملHybrid Fuzzy-PID Application in Boilers to Obtain Optimum Efficiency
Many real time processes have complex, uncertain and nonlinear dynamics. Boilers are nonlinear, time varying, multi-input multi-output (MIMO) systems, whose states generally vary with operating conditions. The major problem in controlling that system is that its drum water pressure and steam flow dynamics include an integrator that results a critically stable behavior. Conventional controller p...

A generalised minimum variance controller is developed for linear time-varying systems. The plants to be controlled are described using a controlled autoregressive moving average model and are exponentially stable. Both, the plant parameters and the noise variance are time-varying. The generalised minimum variance cost functional is the sum of a tracking error variance between a filtered plant ...

Abstract: A flexible controller for optimal control of linear time-varying stochastic systems with multiple time delays is developed. The plants to be controlled are represented using a multi-input multi-output controlled autoregressive moving average model. The delays are described using a diagonal matrix. Input and output filters in the form of linear time-varying moving average operators are...
