Pneumatic position servo system with artificial muscles described in this paper represents feedback control system with non-linear compensation controller of state variables. The designed system demonstrates the operating characteristics that are significantly more favorable than the original characteristics without compensation and they are similar to the properties of the linear system. Such system has principally a shorter control time, significantly lower dynamic control error and it allows apply larger constants of the controller. Following an increased invariance of system against disturbances and also its parametric invariance (robustness) occur.

Current Source Converter

Current source converter (CSC) can control power transfer between superconducting coil and the AC power system, which is the key component of superconducting magnetic energy storage (SMES). This paper presents an improved state-feedback control for CSC of SMES. Adopting the discretization method, the design of decoupled state-feedback control system is simple and straight. To overcome the drawbacks of the discretization method and improve the control system dynamics, the effect of the control time delay is considered. Furthermore, by selecting the current error vector and the output voltage error vector as the additional state variables, a linear state feedback loop is added to the control system to achieve the feature of deadbeat. The steady state performance and dynamic response are investigated. MATLAB simulation is performed to evaluate the performance of the proposed control method.
