CVCF (constant voltage, constant frequency) inverters are electronic devices used to supply AC loads from DC storage elements such as batteries or photovoltaic cells. These devices are used to feed different kinds of loads; this uncertainty requires that the controller fulfills robust stability conditions while keeping required performance. To address this, a robust H ∞ design is proposed based on resonant control to track a pure sinusoidal voltage signal and to reject the most common harmonic signals in a wide range of loads. The design is based on the definition of performance bounds in error signal and weighting functions for covering most uncertainty ranges in loads. Experimentally, the H ∞ controller achieves high-quality output voltage signal with a total harmonic distortion less than 2%.

Hydrolic system is tecknology wich uses fluid, work fluid that is used is oil with viscosity number of 10 SAE. This system work based on the principle of Pascal Low, that is if fluid given pressure, so that pressure will go to all direction by not added or less its pressure. By calculating of type H design hoist car system where as can be result teol that the permession strength of force material is bigger than the happenned strength of force material b = 9.25 kg/mm2  b =0.34 kg/mm2 and g= 70,98 kg/mm2  g= 10,46 kg/mm2. So that the construction of type H design hoist car system by using of material BJ 37 is said saved and strong to be used. On this type H design hoist car system based on SNI 05-3659-1995 which is about hydrolic fluid power with the rod end spherical eyes could be operated perfectly to hoist the car of 2.5 tonnes load. By desig specification of pump hydrolic capasity which is used 0.2 dm3/minutes, power of pump as big 5.4 KW and maximum of load capasity of 2.5 tonnes.
