Engine ISC is a difficult problem because of troublesome characteristics such as severe process nonlinearities, variable time delays, time-varying process dynamics and unobservable system states and disturbances. We demonstrate that recurrent neural network controllers can be trained to handle these difficulties gracefully while achieving good regulator performance for a representative model of 4-cylinder, 1.6 liter engine. Empirical results clearly illustrate that neural network controllers with relatively large amounts of internal feedback provide more robust performance for the ISC problem than do neural network controllers that are static or contain limited internal recurrent connections.","PeriodicalId":162700,"journal":{"name":"1993 American Control Conference","volume":"12 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134333182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This conflicting action is often due to geometric modeling error or, in the case of independently controlled system, mismatch between the reference trajectories of the controllers. The proposed control scheme resolves the conflicting actions via a `mutual learning' process. The adaptive mechanism of each controller modifies its reference trajectory so as to adapt to others. It is shown that a common reference trajectory will eventually be reached by all the controllers. This adaptation process is carried out without explicit communication between the controllers. The proposed scheme was verified by computer simulations and experiments on a dual-manipulator system.","PeriodicalId":162700,"journal":{"name":"1993 American Control Conference","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131771582","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The regulated variable is the deflection at the tip of a flexible beam attached to an inertia wheel base which is subject to a disturbance torque. The control torque affects the base wheel through a coupling which has both compliance and variable backlash. The performance specifications include disturbance attenuation and rapid slewing at the tip. The designs are based on an analytically derived continuous-time model which is tuned in accordance with the measured data. The model consists of an interconnection of a linear time-invariant part and piecewise-linear algebraic nonlinearities modeling friction and backlash. The candidate designs must be based on available measurements only; more-over, the final discrete-time control law must be executable with the real-time controller hardware limitations at hand.","PeriodicalId":162700,"journal":{"name":"1993 American Control Conference","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133508050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
