Gain Scheduling with Guardian Maps for Longitudinal Flight Control

Gain Scheduling for H - In nity Controllers : A Flight Control

A new approach to gain scheduling linear dynamic controllers is illustrated on a pitch-axis autopilot design problem. In this application the linear controllers are designed at distinct operating conditions by H-Innnity methods. The gain scheduling procedure uses particular features of both the linear dynamic controllers and the controller connguration to remove so-called hidden coupling terms ...

Robust Stabilization Control Based on Guardian Maps Theory for a Longitudinal Model of Hypersonic Vehicle

A typical model of hypersonic vehicle has the complicated dynamics such as the unstable states, the nonminimum phases, and the strong coupling input-output relations. As a result, designing a robust stabilization controller is essential to implement the anticipated tasks. This paper presents a robust stabilization controller based on the guardian maps theory for hypersonic vehicle. First, the g...

Fuzzy gain scheduling of PID controller for stiction compensation in pneumatic control valve

Inherent nonlinearities like, deadband, stiction and hysteresis in control valves degenerate plant performance. Valve stiction standouts as a more widely recognized reason for poor execution in control loops. Measurement of valve stiction is essential to maintain scheduling. For industrial scenarios, loss of execution due to nonlinearity in control valves is an imperative issue that should be t...

Fuzzy Gain Scheduling For Improved PID Control

The present paper describes the development of a simple yet effective gain scheduling type fuzzy PID controller algorithm that can employ fuzzy adaptation to dynamically vary conventional PID controller gain(s). While one scheme can dynamically vary the reset rate only, an even improved scheme can effectively vary both proportional gain and reset rate of a PID controller simultaneously, employi...
