Output Ripple Performance Evaluation and Comparison of 2L-VSI and 3L-VSI Considering the Spectral Characteristics
Özkan, Ziya; Hava, Ahmet Masum (2015-06-05)
In this paper, two-level and three-level voltage source inverters (2/3L-VSIs) with popular pulse width modulation (PWM) methods are investigated in terms of their output (ac-side) voltage and current ripple spectral characteristics and waveform quality properties such as peak-to-peak ripple, rms ripple, and weighted total harmonic distortion. As the switching frequency and the filter size influence the output waveform quality, the inverter efficiency (loss) constraint on the switching frequency, and the siz...
Output-feedback control of linear time-varying and nonlinear systems using the forward propagating Riccati equation
Prach, Anna; Tekinalp, Ozan; Bernstein, Dennis S. (2018-04-01)
For output-feedback control of linear time-varying (LTV) and nonlinear systems, this paper focuses on control based on the forward propagating Riccati equation (FPRE). FPRE control uses dual difference (or differential) Riccati equations that are solved forward in time. Unlike the standard regulator Riccati equation, which propagates backward in time, forward propagation facilitates output-feedback control of both LTV and nonlinear systems expressed in terms of a state-dependent coefficient (SDC). To invest...
Output feedback stabilization of nonlinear dual-rate sampled-data systems via an approximate discrete-time model
Ustunturk, Ahmet (2012-08-01)
The problem of output feedback stabilization of nonlinear sampled-data control systems is considered under the low measurement rate constraint. A dual-rate control scheme is proposed that utilizes a numerical integration scheme to approximately predict the missing output values between measured output samples. It is shown that if an observer-based output feedback controller that semiglobally practically asymptotically (SPA) stabilizes the single-rate sampled-data plant model is given, then the SPA stability...
Output voltage control of a four-leg inverter based three-phase UPS utilizing stationary frame resonant filter banks
Hava, Ahmet Masum (2007-09-05)
An all scalar PWM and control approach for the four-leg inverter based three phase transformerless UPS is proposed. The output voltage of each phase is controlled independently and its controller is formed by a stationary frame resonant filter bank accompanied with proportional control and output capacitor current based active damping loops. The resonant filter bank consists of the fundamental component controller and one controller for each dominant harmonic. The simple to implement scalar control method e...
Output voltage control of a four-leg inverter based three-phase ups by means of stationary frame resonant filter banks
Demirkutlu, Eyyüp; Hava, Ahmet Masum; Department of Electrical and Electronics Engineering (2006)
A method for high performance output voltage control of a four-leg inverter based three-phase transformerless UPS is proposed. Voltage control loop is employed and the method employs stationary frame resonant filter controllers for the fundamental and harmonic frequency components. A capacitor current feedback loop provides active damping and enhances the output voltage dynamic performance. The controller design and implementation details are given. Linear and nonlinear loads for balanced and unbalanced loa...
