Guidance panel CP (2) is connected with software module SM (9) on the electronic stencil EM (3).
Start the utility model, electronic stencil EM (3) on the basic templates BM (1), power template PM (4), power interface template PI (5) and excitation control template EC (6) are all in running order, and corresponding operation sequence can be implemented by guidance panel CP (2).
On electronic stencil EM (3), double-core central processor CPU (7) is in running status, and the armature circuit of direct current machine M (14) and the relevant information of energized circuit are carried out quick computing, information stores, logic determines and data processing.Software module SM (9) on the electronic stencil EM (3) is stored among the flash memory flash EPROM (8) with the form of controlled function piece, be provided with the software functional block of technology controlling and process among the software module SM (9), comprise basic ramp function generator, speed calculation, switching value signal processing, diverter switch, timer, arithmetical operation function, analog, quadratic behavior curve, or the like.When using software module SM (9), only need setup parameter, need not program.The software module SM (9) that has set parameter can be with each software function block chaining, thereby realizes drive controlling and function of logic.
On electronic stencil EM (3), because the effect of double-core central processor CPU (7), flash memory flashEPROM (8) and software module SM (9), the utlity model has failure diagnosis and troubleshooting capability, comprise phase shortage, overcurrent, overvoltage, owe Fault Diagnosis and processing such as magnetic and hypervelocity governing system, and temperature rise curve that can analog DC motor M (14) is monitored the superheat state of direct current machine M (14).
On power template PM (4), speed regulator ASR (10) and current regulator ACR (11) all adopt proportional and integral controller PI, and these two adjusters all have amplitude limiter, and the two adopts the string utmost point to connect.
Speed regulator ASR (10) is the outer shroud adjuster, also is leading adjuster, and it can make motor speed follow given voltage U 1 (15) in time and change.Because that speed regulator ASR (10) adopts is proportional and integral controller PI, thereby the rotating speed floating can make systematic steady state the time.The amplitude limit value of speed regulator ASR (10) is determining the maximum direct current Id (21) of direct current machine M (14), and load disturbance is had inhibitory action.
