Feedforward Control for Descriptor System with Unmeasurable Disturbance
نویسندگان
چکیده
This paper develops a design of feedforward control for descriptor system with unmeasurable disturbance which are either nonregular or if it is regular, has impulsive mode. To solve this problem, we will transform descriptor system into regular state space system using the output feedback. First, fault detection and isolation(FDI) approach using sliding mode observer is applied for estimating unmeasurable disturbance. Secondly, with the approximation of disturbance, the feedforward controller which is composed of both tracking the reference model and rejecting an influence is designed by solving a full-information approach for augmented system with a nominal control constraint.

Multi-objective H =H1 fault detection observer design for Takagi–Sugeno fuzzy systems with unmeasurable premise variables: descriptor approach
This paper investigates the problem of robust fault detection observer design for nonlinear Takagi–Sugeno models with unmeasurable premise variables subject to sensor faults and unknown bounded disturbance. The main idea is to synthesize a robust fault detection observer by means of a mixed H =H1 performance index. The considered observer is used to estimate jointly states and faults. Using the...

This paper presents a decentralised control approach for the hydraulic motor torque provided by a hydrostatic transmission. Based on a control-oriented model of the hydrostatic transmission, a quasi-linear state-space representation with both state-dependent and input-dependent matrices is derived. Using extended linearisation techniques, a combined feedforward and feedback control is designed....
متن کاملAn LPV Approach to Sensor Fault Diagnosis of Robotic Arm
One of the major challenges in robotic arms is to diagnosis sensor fault. To address this challenge, this paper presents an LPV approach. Initially, the dynamics of a two-link manipulator is modelled with a polytopic linear parameter varying structure and then by using a descriptor system approach and a robust design of a suitable unknown input observer by means of pole placement method along w...

متن کاملProcess Monitoring and Feedforward Control for Proactive Quality Improvement
Process adjustment strategy is an important part of the process improvement methods, which is also called engineering process control (EPC), and it is often integrated with statistical process control (SPC) to improve the process control performance. While feedback control is used to compensate for the output deviation, feedforward control is a proactive control strategy based on a direct measu...
