摘要： 複数の質量流量制御装置について、ある制御条件のもとで、ある質量流量制御装置のパラメータを調整し、調整されたパラメータを制御条件と関連付けてサーバに記憶させる。次に、サーバに蓄積されたデータから制御条件が共通するデータを抜き出して、抜き出されたデータに基づいてパラメータの初期値を決定し、決定されたパラメータの初期値を、共通する制御条件と関連付けてサーバに記憶させる。このようにして決定されたパラメータの初期値を用いて、質量流量制御装置の調整を行う。これにより、質量流量制御装置の調整をより少ない手順で完了するとともに、質量流量制御装置の調整の不具合の発生を未然に防止することができる。

摘要： Certain embodiments provide a vacuum generation system with a cascade PID controller, a proportional valve, and a vacuum generator. The cascade PID controller allows the vacuum generation system to control the operating range of supply air pressure that is provided to the vacuum generator. By controlling the operating range of the supply air pressure, the vacuum generation system is able to avoid entering the decreasing or non-monotonic region of the vacuum generator.

摘要： A synchronous machine (12) comprises a stator (22) with stator windings (18) connected with stator terminals (20) to an electrical grid (16) and a rotor (24) with rotor windings (26) rotatable mounted in the stator (22), wherein a voltage regulator (14) of the synchronous machine (12) is adapted for outputting an excitation signal ( u ) to adjust a current in the rotor windings (26) for controlling the synchronous machine (12). A method for determining control parameters (54) for the voltage regulator (14) comprises: receiving a first time series of values of the excitation signal ( u ) and a second time series of measurement values of a terminal voltage ( y ) in the stator terminals (20), wherein the first time series and the second time series are acquired over a time interval; determining coefficients (52) of a system transfer function ( G(s) ) of the synchronous machine (12), wherein the system transfer function (G(s j) is a rational function, wherein the coefficients (52) of the system transfer function ( G(s) ) are determined recursively with a regression analysis with instrumental variables based on the first time series as system input and the second time series as system output; and determining the control parameters (54) for the voltage regulator (14) from the coefficients (52) of the system transfer function ( G(s) ) by comparing a closed loop transfer function formed of a controller transfer function ( C(s) ) of the voltage regulator (14) and the system transfer function ( G(s) ) with a desired closed loop transfer function.

摘要： An atherectomy system includes a drive mechanism that is adapted to rotatably actuate an atherectomy burr and a controller that is adapted to regulate operation of the drive mechanism. In some cases, the drive mechanism includes a drive cable that is coupled with the atherectomy burr and an electric drive motor that is adapted to rotate the drive cable. The controller is adapted to regulate operation of the electric drive motor such that the drive mechanism emulates one or more performance parameters of an air turbine.
