This paper presents an Internal Model Control based structure to realise fault tolerance towards sensor faults. The proposed design implicitly embeds fault detection and controller elements requirements with considerations to stability and robustness towards uncertainties besides multiple faults environment. The performance of the proposed controller is demonstrated via multi input multi output...

robust control design of vehicles addresses the effect of uncertainties on the vehicle’s performance. in present study, the robust optimal multi-objective controller design on a non-linear full vehicle dynamic model with 8-degrees of freedom having parameter with probabilistic uncertainty considering two simultaneous conflicting objective functions has been made to prevent the rollover. the obj...

This paper attempts to propose a single-input CMAC control system where the controller is implemented by a one-dimensional CMAC. The single-input CMAC control system adopts two learning stages. An off-line learning stage is to enable the output behavior of the CMAC to approximate the control surface of a fuzzy PD-type controller. An on-line learning stage is followed to make the proposed contro...

Abstract: Whenever the fabrication process consists of several steps and the dynamic modification of individual steps or step sequences of the process is allowed, multi-step feedback and feed-forward control can be utilized to improve the quality of the fabrication process. Feedback and feed-forward control have been identified as important features of the semiconductor manufacturing facility o...

Nonminimum Phase Discrete Time Models Yuping Gu and Masayoshi Tomizuka Department of Mechanical Engineering University of California at Berkeley, Berkeley, CA 94720-1740 [email protected] [email protected] Abstract This paper is concerned with performance enhancement of tracking control systems by multi-rate control. The feedback controller is updated at the same rate as the sampling r...

The paper introduces a class of zero-sum games between the adversary and controller as a scenario for a ‘denial of service’ in a networked control system. The communication link is modeled as a set of transmission regimes controlled by a strategic jammer whose intention is to wage an attack on the plant by choosing a most damaging regime-switching strategy. We demonstrate that even in the one-s...

Multi-port converter with three active full bridges, two series-resonant tanks and a Multi-winding transformer is proposed. It uses a single power conversion stage with high-frequency link to control power flow between batteries, load and a renewable source such as fuel cell. The converter has capabilities of bidirectional power flow in the battery and the load port. Use of series-resonance aid...

The focus of the paper is to solve the stability problem of a multi-agent system composed of nonholonomic vehicles. The multi-vehicle formation is achieved following a first step where targets are identified and attractive sets circumscribing this are constructed. In a second step, the initial position and orientation of each agent is specified. In a last stage, a decentralized controller integ...
