Our previous study shows that its possibility to integrate the feedback linearization law when some conditions satisfied. In the present study, we first simplify the structure of the FL-PIM controller to reduce the calculation cost. Then, the proposed FL-PIM method is verified through the experiment using a single-link elastic-joint robot.","PeriodicalId":391189,"journal":{"name":"2022 SICE International Symposium on Control Systems (SICE ISCS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123410500","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}

For a circular path-following control of a vehicle, rotational coordinate transformation is applied to the vehicle model. However, through numerical simulations, we found that undershoot responses occurred under certain initial conditions of the vehicle. The occurrence of undershoot responses indicates that the output in the transient response moves in the opposite direction to the step reference value and is related to the zeros of the transfer function. In this study, we focus on the zeros of the transfer function of the vehicle by applying rotational coordinate transformation to clarify the conditions for the undershoot responses.","PeriodicalId":391189,"journal":{"name":"2022 SICE International Symposium on Control Systems (SICE ISCS)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127008068","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}

In the particular case of autonomous driving and cruise control, the inherent nonlinearity and complexity of the physical dynamics result in a highly nonconvex control problem, which becomes even more challenging if one is to further account for energy saving constraints. Leveraging on recent advancements, we propose a solution based on PANOC [19], a fast optimization solver which can cope with nonconvex problems and enjoys very low computational requirements, provided that some inner subproblems can be solved at negligible effort. In order to account for this binding requirement of the algorithm, we propose a piecewise affine approximation strategy for the fuel consumption model based on the Douglas– Peucker algorithm [7]. The effectiveness of the approach is showcased with numerical simulations on a real-time adaptive cruise control problem for fuel consumption optimization.","PeriodicalId":391189,"journal":{"name":"2022 SICE International Symposium on Control Systems (SICE ISCS)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123524102","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 LMI–based design of the linear part of the composite controller is based on the nominal linear system and is formulated as a multi–objective H-infinity minimization problem for disturbance rejection, performance (with various degrees of control aggressiveness) and minimization of the 2-norm of the state feedback gains. The design of the nonlinear part is based on Lyapunov redesign (the “unit vector” variant of Sliding Mode Control), which is a continuous nonlinear state feedback guaranteeing Uniform Ultimate Boundedness (UUB) of the closed–loop system. Explicit formulae are derived for the size of the UUB region and the Radius of the Attracting Ball (RAB), indicating a tradeoff between aggressiveness and chattering. The numerical example of a single input system demonstrates the efficacy of the proposed methodology.","PeriodicalId":391189,"journal":{"name":"2022 SICE International Symposium on Control Systems (SICE ISCS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114480042","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}

To design and analyze a digital controller of the CMG, it requires a discrete-time model, which can be derived by discretizing a continuous-time model. Since the CMG is nonlinear and has an affine constrain for a nonholonomic system, its linear approximation becomes uncontrollable and unavailable for control design. This paper proposed a discrete-time model for the CMG system, which does not use the linear approximation of the continuous-time model, by using a method called continualized discretization proposed. Simulation results show that the proposed model yields better performances than the conventional forward difference model in reproducing the dynamical characteristic of the continuous-time model, even for a large sampling interval and fast dynamical response.","PeriodicalId":391189,"journal":{"name":"2022 SICE International Symposium on Control Systems (SICE ISCS)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117211438","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 effectiveness of the proposed method is verified by analyzing the lower leg during knee flexion and extension by three healthy men in their 20s using ultrasound diagnostic device and confirming the physiological movement of screw-home movement(SHM) during knee flexion and extension movement. From the experimental results, SHM is confirmed during knee flexion and extension movements in each subject.
