  • pi state space current control of grid connected pwm converters with lcl filters
    IEEE Transactions on Power Electronics, 2010
    Co-Authors: J Dannehl, F W Fuchs, Paul Thogersen
    Abstract:

    Design and analysis of PI state space control for grid-connected pulsewidth modulation (PWM) converters with LCL filters based on pole placement approach is addressed. State space control offers almost full controllability of system dynamic. However, pole placement design is difficult and usually requires much experience. In this paper, a suitable pole placement strategy is proposed, which ensures fulfilling the requirements, which are commonly specified with respect to rise time, overshoot, and proper resonance damping. Controller Parameter expressions are derived in terms of system Parameters and specified poles and zeros. Hence, straightforward Controller tuning for a particular system setting is possible. Performance is analyzed by means of transfer function-based calculations, simulations with MATLAB, and experimental tests. Dynamic performance and robustness against grid impedance variations are addressed as well as harmonic rejection capability and other practical issues.

  • multi objective digital pid Controller design in Parameter space and its application to automated path following
    IEEE Access, 2021
    Co-Authors: Haoan Wang, Sukru Yaren Gelbal, Levent Guvenc
    Abstract:

    This paper presents a multi-objective digital PID Controller design method using the Parameter space approach of robust control. Absolute stability is treated first by finding the digital PID Controller gain Parameter space corresponding to closed loop poles being inside the unit circle. Additionally, phase margin, gain margin and a mixed sensitivity bound are treated as frequency domain constraints. Determination of digital PID Controller Parameter space regions satisfying these constraints is presented. All of these regions are superimposed to obtain a multi-objective digital PID Controller gain Parameter space solution region. The path following Controller design of an automated driving vehicle is used as an example to illustrate the method. This multi-objective Parameter space design approach can be extended to other digital Controller forms also.
