Novel Approach To Fuzzy Logic Controller Design For Systems With Deadzones, Jong-Hwan Kim, Jong-Hwan Park, Seon-Woo Lee, Edwin K. P. Chong Oct 1992

Novel Approach To Fuzzy Logic Controller Design For Systems With Deadzones, Jong-Hwan Kim, Jong-Hwan Park, Seon-Woo Lee, Edwin K. P. Chong

Department of Electrical and Computer Engineering Technical Reports

Existing fuzzy control methods do not perform well when applied to systems containing nonlinearities arising from unknown deadzones. In particular, we show that a conventional fuzzy logic controller applied to a system with a deadzone suffers from poor transient performance and a large steady-state error. In this report, we propose a novel two-layered fuzzy logic controller for controlling systems with deadzones. The two-layered control structure consists of a fuzzy logic-based precompensator followed by a conventional fuzzy logic controller. Our proposed controller exhibits superior transient and steady-state performance compared to conventional fuzzy controllers. In addition, the controller is robust to variations …


Time Complexity Of A Path-Formulated Optimal Routing Algorithm, John K. Antonio, Wei K. Tsai, G. M. Huang Oct 1992

Time Complexity Of A Path-Formulated Optimal Routing Algorithm, John K. Antonio, Wei K. Tsai, G. M. Huang

Department of Electrical and Computer Engineering Technical Reports

A detailed analysis of convergence rate is presented for an iterative path formulated optimal routing algorithm. The primary objective is to quantify, analytically, how the convergence rate changes as the number of nodes in the underlying graph increases. The analysis is motivated by a particular path formulated gradient projection algorithm that has demonstrated excellent convergence rate properties through extensive numerical studies. In particular, the empirical data suggests that the number of iterations required for convergence to within a small fraction of the optimal cost is relatively independent of the number of nodes. Deriving a correspondingly tight analytical bound for the …

Comparative Study Of Motion Control Methods For A Nonlinear System, Daniel J. Pack,, Min Meng, A. C. Kak Sep 1992

Comparative Study Of Motion Control Methods For A Nonlinear System, Daniel J. Pack,, Min Meng, A. C. Kak

Department of Electrical and Computer Engineering Technical Reports

What led to the novel ideas, some of them theoretical, presented in this paper is our highly experimental approach to nonlinear control. We actually designed and fabricated a two-link inverted pendulum, and learned about the relationships and the trade offs that exist in such a device. In the context of controlling an inverted pendulum, the novel ideas presented in this paper relate to i) the design of a fuzzy logic controller; ii) the design of a neuralnetwork controller; and iii) experimental implementation of a nonlinear controller based on differential-geometric notions; etc. etc. These novel ideas are presented in a comparative …


Design Methodology For Low Speed Variable Reluctance Motors, John R. Suriano Sep 1992

Design Methodology For Low Speed Variable Reluctance Motors, John R. Suriano

Department of Electrical and Computer Engineering Technical Reports

Lowering the gear reduction in actuators by utilizing high-torque low-speed motors enables the use of less expensive and simpler gear systems and decreases the overall system inertia. Variable reluctance machines can produce high torque at low speeds. Their static torque, a critical quantity for determination of low speed operation, is colnpared for three variable reluctance motor design variations using linear analysis. Saturation effects, which are crucial to the accurate determination of static torque, are modeled using a dual energy technique first proposed by Lord Rayleigh. Dual energy techniques utilizing flux tubes and magnetomotive force slices are developed into a numerical …
