For a servo plant with an integrator, analytical tuning formulas for phase lead compensators with both gain and phase margin specifications are derived in this paper. Comparing with other tuning methods, this method is simple with a short tuning time. Simulation results under two typical cases show that this method is general, too. Copyright c ©2005 IFAC

Working with input-output transfer functions in the frequency domain and exploiting a formulation involving generalized Sylvester resultants, we are able to derive necessary and sufficient conditions for generic invariant factor assignment, in several cases, using proper dynamic output feedback compensators.

To ensure the secure operation of a multiterminal high-voltage DC (MTDC) grid, power flow controllers (PFCs) are deployed to regulate current distribution among different transmission lines. Besides management, PFCs envisioned provide range functionalities such as stability enhancement, oscillation damping, and ancillary services host MTDC grid. This paper extends functionality PFC active dampi...

This paper deals with nonlinear compensation in code-division multiple-access communications systems. We analyze the performance of the generalized cerebellar model articulation controller neural network in two problems: predistortion in nonlinear transmitters and adaptive interference cancellation in multiuser and multipath scenarios. Our examples demonstrate the performance of the compensator...

This paper presents a study on Proportional Resonant (PR) current control with additional PR harmonic compensators for Grid Connected Photovoltaic (PV) Inverters. Both simulation and experimental results will be presented. Testing was carried out on a 3kW Grid-Connected PV Inverter which was designed and constructed for this research. Keywords—Inverters, Proportional-Resonant Controllers, Harmo...

For nonlinear control systems with two inputs we consider the problem of dynamic feedback linearization. For a restricted class of dynamic compensators that correspond to adding chains of integra-tors to the inputs, we give an upper bound for the order of the compensator that needs to be considered. Moreover, we show by an example that this bound is sharp.

Abstruct-The problem of linear system decoupling is examined based on recent results on linear feedback. New insight is obtained, through which resolution of the decoupling problem is accomplished by calculations, performed directly on the given transfer matrix. Computation of the decoupling compensators follows by easy constructions. The problem of feedback block decoupling with internal...

Experimental validation in addition to detailed modeling and simulation of a new transformer-less series compensator for linecommutated HVDC rectifier terminal is presented. The compensator employs very small capacitors compared to those in conventional shunt compensators or fixed series capacitors for reactive power compensation of such links. The proposed device demonstrates fundamental-frequ...
