The present invention provides a motor control system and method thereof. The motor control system comprises a motor controller and a compensation device. The motor controller is used for generating a motor control output according to a reference signal and a first signal. The compensation device is used for generating a compensated motor control output according to the motor control output and a second signal. Moreover, the compensation device utilizes the compensated motor control output to reduce the steady-state phase error between the first signal and the reference signal.

A substrate etching method and a substrate processing device, the substrate etching method includes: S1: placing a substrate to be processed into a reaction chamber; S2: supplying etching gas into the reaction chamber; S3: turning on an excitation power supply to generate plasma in the reaction chamber; S4: turning on a bias power supply to apply bias power to the substrate; S5: turning off the bias power supply, and meanwhile, starting to supply deposition gas into the reaction chamber; S6: stopping supply of the deposition gas into the reaction chamber, and meanwhile, turning on the bias power supply; S7: repeating steps S5-S6, until the etching process is completed. In the whole etching process, the etching operation is always performed, and the deposition operation is performed sometimes. Therefore, during the deposition operation, the plasma in the reaction chamber can etch away at least a part of deposited polymers formed by the deposition operation on a sidewall of an etched section, so that the sidewall of the etched section of the substrate is smooth.

The invention discloses a control method and a device for an initial openness of an electronic expansion valve and an air conditioning system. The method comprises the steps of: obtaining a present outdoor temperature; calculating a proportional parameter corresponding to the present outdoor temperature based on preset calculation rules; calculating a target operation frequency of an air conditioning set; calculating a product between the proportional parameter and the target operation frequency of the air conditioning set to obtain an initial openness numerical value of the electronic expansion valve; and controlling the electronic expansion valve to operate according to the initial openness numerical value. The method can enable the electronic expansion valve to work according to the proper initial openness so as to help the air conditioning system to quickly enter a stable state; and compared with the prior art, a certain energy saving effect is achieved in the operation process.

The invention discloses a shock-absorbing adjustment mechanism for a plane mirror. The plane mirror is suspended on the main structure by a thin steel belt through half-threaded bolts. The side thread adjustment rod of the plane mirror, the back adjustment mechanism, the back thread adjustment rod, and the bottom thread adjustment rod jointly realize the shock absorption and high-precision adjustment function of the plane mirror. The advantage of the shock-absorbing adjustment mechanism is that the plane mirror can quickly enter a stable state through the high-precision adjustment mechanism under the condition that the plane mirror is only slightly deformed.
