1) To establish minimal realizations of low-degree impedances with application to passive controller design for vehicle suspension, vibration isolators, and dynamic vibration absorbers: (i) realizations of biquadratic impedances as six-element non-series-parallel networks and of a sub-class that contains double poles and zeros, (ii) minimal mechanical realizations of a class of low-degree functions, and (iii) design of low-degree passive controllers for mechanical vibration control systems; 2) To investigate restricted one-port networks with application to vehicle suspension and realization procedure design: (i) further investigation of one-port mechanical networks containing one damper, one inerter, and several springs, and their application to vehicle suspension systems, (ii) establishment of transformerless realization procedures for arbitrary positive-real functions, and (iii) design of a transformerless realization procedure for a class of positive-real functions of any degree; 3) To develop the synthesis of multi-port passive networks based on modern systems theory and to investigate realizations of n-port resistive networks; 4) To design inerter-based vibration isolators for distributed systems: (i) optimization for fixed-structured inerter-based isolators and (ii) inerter-based isolator design under restricted realization conditions; 5) To construct a wireless semi-active inerter prototype and propose effective control algorithms for semi-active vibration control systems with a semi-active inerter.
